The motivation for this new DiagnosticConsumer is to provide a way for tools invoking the compiler
to get its diagnostics via a libclang interface, rather than textually parsing the compiler output.
This gives us flexibility to change the compiler's textual output, but have a structured data format
for clients to use to get the diagnostics via a stable API.
I have no tests for this, but llvm-bcanalyzer so far shows that the emitted file is well-formed.
More work to follow.

as part of the hash rather than ignoring them. This means we'll end up
building more module variants (overall), but it allows configuration
macros such as NDEBUG to work so long as they're specified via command
line. More to come in this space.

increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.
This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.
Most, though, it involved a perl script to translate a ton
of test cases.
Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there.
The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs.
Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend.
I tried to match GCC's behavior as close as possible

OpenCL is different from AltiVec in the way it supports vector literals. OpenCL
is strict with regards to semantic checks. For example, implicit conversions
and explicit casts between vectors of different types are disallowed.

Microsoft specific tweaking will now fall into 2 categories:
- fms-extension: Microsoft specific extensions that should never change the meaning of an otherwise well formed code. Currently map to LangOptions::Microsoft. (To be clearer, I am planning to change the name to LangOptions::MicrosoftExt).
- fms-compatibility: Really a MSVC emulation mode. Map to LangOptions::MicrosoftMode. Can change the meaning of an otherwise standard conformant program.

target triple to separate modules built under different
conditions. The hash is used to create a subdirectory in the module
cache path where other invocations of the compiler (with the same
version, language options, etc.) can find the precompiled modules.

language options. Use that .def file to declare the LangOptions class
and initialize all of its members, eliminating a source of annoying
initialization bugs.
AST serialization changes are next up.

where the compiler will look for module files. Eliminates the
egregious hack where we looked into the header search paths for
modules.

feature akin to the ARC runtime checks. Removes a terrible hack where
IR gen needed to find the declarations of those symbols in the translation
unit.

from the given source. -emit-module behaves similarly to -emit-pch,
except that Sema is somewhat more strict about the contents of
-emit-module. In the future, there are likely to be more interesting
differences.

__unknown_anytype, and rewrite such message sends correctly.
I had to bite the bullet and actually add a debugger support mode for this
one, which is a bit unfortunate, but there really isn't anything else
I could imagine doing; this is clearly just debugger-specific behavior.

This is a new mode of migration, where we avoid modifying the original files but
we emit temporary files instead.
<path> will be used to keep migration process metadata. Currently the temporary files
that are produced are put in the system's temp directory but we can put them
in the <path> if is necessary.
Also introduce new ARC migration functions in libclang whose only purpose,
currently, is to accept <path> and provide pairs of original file/transformed file
to map from the originals to the files after transformations are applied.
Finally introduce the c-arcmt-test utility that exercises the new libclang functions,
update arcmt-test, and add tests for the whole process.

structure to hold inferred information, then propagate each invididual
bit down to -cc1. Separate the bits of "supports weak" and "has a native
ARC runtime"; make the latter a CodeGenOption.
The tool chain is still driving this decision, because it's the place that
has the required deployment target information on Darwin, but at least it's
better-factored now.

use an "IgnoreSysRoot" argument. HeaderSearchOptions had been using the
opposite form with "IsSysRootRelative", which made for much confusion when
looking at true/false values in calls in AddPath. No functional change.
