This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.

This patch enabled code completion for ClangREPL. The feature was built upon
three existing Clang components: a list completer for LineEditor, a
CompletionConsumer from SemaCodeCompletion, and the ASTUnit::codeComplete method.
The first component serves as the main entry point of handling interactive inputs.
Because a completion point for a compiler instance has to be unchanged once it
is set, an incremental compiler instance is created for each code
completion. Such a compiler instance carries over AST context source from the
main interpreter compiler in order to obtain declarations or bindings from
previous input in the same REPL session.
The most important API codeComplete in Interpreter/CodeCompletion is a thin
wrapper that calls with ASTUnit::codeComplete with necessary arguments, such as
a code completion point and a ReplCompletionConsumer, which communicates
completion results from SemaCodeCompletion back to the list completer for the
REPL.
In addition, PCC_TopLevelOrExpression and CCC_TopLevelOrExpression` top levels
were added so that SemaCodeCompletion can treat top level statements like
expression statements at the REPL. For example,
clang-repl> int foo = 42;
clang-repl> f<tab>
From a parser's persective, the cursor is at a top level. If we used code
completion without any changes, PCC_Namespace would be supplied to
Sema::CodeCompleteOrdinaryName, and thus the completion results would not
include foo.
Currently, the way we use PCC_TopLevelOrExpression and
CCC_TopLevelOrExpression is no different from the way we use PCC_Statement
and CCC_Statement respectively.

The new patch also fixes clangd and several memory issues that the bots reported
and upload the missing files.

Under the hood this prints the same as `QualType::getAsString()` but cuts out the middle-man when that string is sent to another raw_ostream.

The "parameter list" is the list of fields which should be initialized.
We introduce a new OverloadCandidate kind for this.
It starts to become harder for CC consumers to handle all the cases for
params, so I added some extra APIs on OverloadCandidate to abstract them.
Includes some basic support for designated initializers.
The same aggregate signature is shown, the current arg jumps after the
one you just initialized. This follows C99 semantics for mixed
designated/positional initializers (which clang supports in C++ as an extension)
and is also a useful prompt for C++ as C++ designated initializers must be
in order.

Implementation is based on the "expected type" as used for
designated-initializers in braced init lists. This means it can deduce the type
in some cases where it's not written:
void foo(Widget);
foo({ /*help here*/ });
Only basic constructor calls are in scope of this patch, excluded are:
- aggregate initialization (no help is offered for aggregates)
- initializer_list initialization (no help is offered for these constructors)

Provide signature while typing template arguments: Foo< ^here >
Here the parameters are e.g. "typename x", and the result type is e.g.
"struct" (class template) or "int" (variable template) or "bool (std::string)"
(function template).
Multiple overloads are possible when a template name is used for several
overloaded function templates.

This avoids an unnecessary copy required by 'return OS.str()', allowing
instead for NRVO or implicit move. The .str() call (which flushes the
stream) is no longer required since 65b13610a5226b84889b923bae884ba395ad084d,
which made raw_string_ostream unbuffered by default.

Only the bare name is completed, with no args.
For args to be useful we need arg names. These *are* in the tablegen but
not currently emitted in usable form, so left this as future work.
C++11, C2x, GNU, declspec, MS syntax is supported, with the appropriate
spellings of attributes suggested.
`#pragma clang attribute` is supported but not terribly useful as we
only reach completion if parens are balanced (i.e. the line is not truncated)
There's no filtering of which attributes might make sense in this
grammatical context (e.g. attached to a function). In code-completion context
this is hard to do, and will only work in few cases :-(
There's also no filtering by langopts: this is because currently the
only way of checking is to try to produce diagnostics, which requires a
valid ParsedAttr which is hard to get.
This should be fairly simple to fix but requires some tablegen changes
to expose the logic without the side-effect.

This is mostly a mechanical change, but a testcase that contains
parts of the StringRef class (clang/test/Analysis/llvm-conventions.cpp)
isn't touched.
Summary:
The basic idea is to walk through the concept definition, looking for
t.foo() where t has the constrained type.
In this patch:
- nested types are recognized and offered after ::
- variable/function members are recognized and offered after the correct
dot/arrow/colon trigger
- member functions are recognized (anything directly called). parameter
types are presumed to be the argument types. parameters are unnamed.
- result types are available when a requirement has a type constraint.
These are printed as constraints, except same_as<T> which prints as T.
Not in this patch:
- support for merging/overloading when two locations describe the same member.
The last one wins, for any given name. This is probably important...
- support for nested template members (T::x<int>)
- support for completing members of (instantiations of) template template parameters

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.

Summary:
The dir component ("somedir" in #include <somedir/fo...>) is considered fixed.
We append "foo" to each directory on the include path, and then list its files.
Completions are of the forms:
#include <somedir/fo^
foo.h>
fox/
The filter is set to the filename part ("fo"), so fuzzy matching can be
applied to the filename only.
No fancy scoring/priorities are set, and no information is added to
CodeCompleteResult to make smart scoring possible. Could be in future.

Currently getting such completions requires source correction, reparsing
and calling completion again. And if it shows no results and rollback is
required then it costs one more reparse.
With this change it's possible to get all results which can be later
filtered to split changes which require correction.

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

CodeCompletionContext had declarations of field and enum inside, both named 'Kind'.
It caused gcc 4.8 to give an incorrent warning when refering to enum as
`enum CodeCompletionContext::Kind`.
Avoid that warning by renaming the private field to CCKind.
