7e561b62d2 [NFC] Refactor DiagnosticBuilder and PartialDiagnostic
PartialDiagnostic misses some functions compared to DiagnosticBuilder.

This patch refactors DiagnosticBuilder and PartialDiagnostic, extracts
the common functionality so that the streaming << operators are
shared.

849c60541b PR47792: Include the type of a pointer or reference non-type template
parameter in its notion of template argument identity.

We already did this for all the other kinds of non-type template
argument. We're still missing the type from the mangling, so we continue
to be able to see collisions at link time; that's an open ABI issue.

b62fd436a3 Revert "Recommit [NFC] Refactor DiagnosticBuilder and PartialDiagnostic"
This reverts commit 8e780a1653e6f87755a447e921b8f929d8b70996.

DiagnosticBuilder is a value type, created on the stack everywhere. IMO
we should not be adding a vtable to it, and making very operator<< use a
virtual interface. There are other feasible designs for implementing
this. The original review, D84362, was approved by @tra, who is
responsible for Clang's CUDA support, but it wasn't reviewed by @rsmith
or anyone responsible for clang's diagnostic library.

8e780a1653 Recommit [NFC] Refactor DiagnosticBuilder and PartialDiagnostic
This recommits 829d14ee0a6aa79c89f7f3d9fcd9d27d3efd2b91.

The patch was reverted due to a regression in some CUDA app
which was thought to be caused by this patch. However, investigation
showed that the regression was due to some other issues, therefore
recommit this patch.

allocate the underlying data of Template kind separately, this would reduce AST
memory usage

- TemplateArgumentLocInfo 24 => 8 bytes
- TemplateArgumentLoc  48 => 32 bytes
- DynTypeNode 56 => 40 bytes

ASTContext::.getASTAllocatedMemory changes:
  SemaDecl.cpp 255.5 MB => 247.5MB
  SemaExpr.cpp 293.5 MB => 283.5MB

b481f02814 [Concepts] Placeholder constraints and abbreviated templates
This patch implements P1141R2 "Yet another approach for constrained declarations".

General strategy for this patch was:

- Expand AutoType to include optional type-constraint, reflecting the wording and easing the integration of constraints.
- Replace autos in parameter type specifiers with invented parameters in GetTypeSpecTypeForDeclarator, using the same logic
  previously used for generic lambdas, now unified with abbreviated templates, by:
  - Tracking the template parameter lists in the Declarator object
  - Tracking the template parameter depth before parsing function declarators (at which point we can match template
    parameters against scope specifiers to know if we have an explicit template parameter list to append invented parameters
    to or not).
- When encountering an AutoType in a parameter context we check a stack of InventedTemplateParameterInfo structures that
  contain the info required to create and accumulate invented template parameters (fields that were already present in
  LambdaScopeInfo, which now inherits from this class and is looked up when an auto is encountered in a lambda context).

Resubmit after fixing MSAN failures caused by incomplete initialization of AutoTypeLocs in TypeSpecLocFiller.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

We've been running doxygen with the autobrief option for a couple of

encourage more \brief markers in new code either, this patch removes
them all.

00f70bd933 Remove redundant casts. NFC
So I wrote a clang-tidy check to lint out redundant `isa`, `cast`, and
`dyn_cast`s for fun. This is a portion of what it found for clang; I
plan to do similar cleanups in LLVM and other subprojects when I find
time.

Because of the volume of changes, I explicitly avoided making any change
that wasn't highly local and obviously correct to me (e.g. we still have
a number of foo(cast<Bar>(baz)) that I didn't touch, since overloading
is a thing and the cast<Bar> did actually change the type -- just up the
class hierarchy).

I also tried to leave the types we were cast<>ing to somewhere nearby,
in cases where it wasn't locally obvious what we were dealing with
before.

593d6a168f When merging two deduced non-type template arguments for the same parameter,
fail the merge if the arguments have different types (except if one of them was
deduced from an array bound, in which case take the type from the other).

This is correct because (except in the array bound case) the type of the
template argument in each deduction must match the type of the parameter, so at
least one of the two deduced arguments must have a mismatched type.

This is necessary because we would otherwise lose the type information for the
discarded template argument in the merge, and fail to diagnose the mismatch.

In order to power this, we now properly retain the type of a deduced non-type
template argument deduced from a declaration, rather than giving it the type of
the template parameter; we'll convert it to the template parameter type when
checking the deduced arguments.

e7d82283cd [TrailingObjects] Convert AST classes that had a ASTTemplateKWAndArgsInfo.
So, also:

- Moved the TemplateArgumentLoc array out of the
  ASTTemplateKWAndArgsInfo class (making it a simple fixed-size object),
  to avoid needing to have a variable-length object as part of a
  variable-length object. Now the objects that have a
  ASTTemplateKWAndArgsInfo also have some TemplateArgumentLoc objects
  appended directly.

- Removed some internal-use accessors which became simply a wrapper on
  getTrailingObjects.

- Moved MemberNameQualifier out of the MemberExpr class, renamed it
  MemberExprNameQualifier, because the template can't
  refer to a class nested within the class it's defining.

04ec5bfad8 [TrailingObjects] Convert ASTTemplateKWAndArgsInfo and ASTTemplateArgumentListInfo.
Doing so required separating them so that the former doesn't inherit
from the latter anymore. Investigating that, it became clear that the
inheritance wasn't actually providing real value in any case.

So also:
- Remove a bunch of redundant functions (getExplicitTemplateArgs,
  getOptionalExplicitTemplateArgs) on various Expr subclasses which
  depended on the inheritance relationship.
- Switched external callers to use pre-existing accessors that return the
  data they're actually interested in (getTemplateArgs,
  getNumTemplateArgs, etc).
- Switched internal callers to use pre-existing getTemplateKWAndArgsInfo.

0f62c8d8f8 PR21246: DebugInfo: Emit the appropriate type (cv qualifiers, reference-ness, etc) for non-type template parameters
Plumb through the full QualType of the TemplateArgument::Declaration, as
it's insufficient to only know whether the type is a reference or
pointer (that was necessary for mangling, but insufficient for debug
info). This shouldn't increase the size of TemplateArgument as
TemplateArgument::Integer is still longer by another 32 bits.

Several bits of code were testing that the reference-ness of the
parameters matched, but this seemed to be insufficient (various other
features of the type could've mismatched and wouldn't've been caught)
and unnecessary, at least insofar as removing those tests didn't cause
anything to fail.

(Richard - perchaps you can hypothesize why any of these checks might
need to test reference-ness of the parameters (& explain why
reference-ness is part of the mangling - I would've figured that for the
reference-ness to be different, a prior template argument would have to
be different). I'd be happy to add them in/beef them up and add test
cases if there's a reason for them)

abe1a398e3 Render anonymous entities as '(anonymous <thing>)' (and lambdas as '(lambda at ... )')
For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all
cases.

fdf496cb48 PR19278: Align ASTTemplateArgumentListInfo to match its following dynamic array

94e9eaa4d7 Fix one place I missed that was memcpy'ing TypeLocs in a way that messes
up alignment.

Fixes utilities/tuple/tuple.tuple/tuple.creation/tuple_cat.pass.cpp from the
libc++ testsuite.

b8f6a8ab07 Debug Info: include address-of ('&') operator and qualified names in template argument lists
This fixes several (7 out of 16) cases of PR14492 in the GDB 7.5 test
suite. It seems GDB was bailing out whenever it had even the slightest
problem with the template argument list (& I assume it didn't like
seeing template value parameters that were just simple names - perhaps
assuming that lone names must be types, not values)

6adc78e0df Replace TypeLoc llvm::cast support to be well-defined.
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined
behavior by casting pointers/references to TypeLoc objects to derived types
and then using the derived copy constructors (or even returning pointers to
derived types that actually point to the original TypeLoc object).

Some context is in this thread:
http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html
Though it's spread over a few months which can be hard to read in the mail
archive.

a7d03840e6 Excise <cctype> from Clang (except clang-tblgen) in favor of CharInfo.h.
Nearly all of these changes are one-to-one replacements; the few that
aren't have to do with custom identifier validation.
