This introduces the definitions needed for the Windows on ARM target. Add
target definitions for both the MSVC environment and the MSVC + Itanium C++ ABI
environment. The Visual Studio definitions correspond to the definitions
provided by Visual Studio 2012.

If we ever want three or more aliases, at that point we should put MSVC
warning ids in DiagnosticGroups.td. We can use that to support #pragma
warning.

Fallout from r205261, ensure it doesn't matter how we disable compressed
debug info, even if zlib is missing and that we warn when we don't have
zlib and don't warn when we do, all while silently suppressing these
tests on the systems they weren't intended for...

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

The test was failing because clang-cl changes the default triple
to target MSVC-style Win32. This is kind of wonky, but hasn't been
a problem until we started warning:
warning: unknown platform, assuming -mfloat-abi=soft
Some of the tests in cl-options.c were running with -Werror, causing them
to fail.
Fixing this by FileCheck-ifying those tests instead of using -Werror.

This follows the LLVM change to canonicalise the Windows target triple
spellings. Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment. This is a
mechanical change to convert the triple use to reflect that change.

In gcc using -Ofast forces linking of crtfastmath.o.
In the current clang crtfastmath.o is only linked when -ffast-math/-funsafe-math-optimizations passed. It can lead to performance issues, when using only -Ofast without explicit -ffast-math (I faced with it).
My patch fixes inconsistency with gcc behaviour and also introduces few tests on it.

/Gy is equivalent to -ffunction-sections.
/Gy- is equivalent to -fno-function-sections.
Currently, LLVM doesn't do anything interesting with -ffunction-sections
under WinCOFF.

This change turns -fsanitize-memory-track-origins into
-fsanitize-memory-track-origins=[level] flag (keeping the old one for
compatibility). Possible levels are 0 (off), 1 (default) and 2 (incredibly
detailed). See docs (part of this patch) for more info.

This is because the PCH is tied to the module files, if one of the module files changes or gets removed
the build system should re-build the PCH file.

When enabled, always validate the system headers when loading a module.
The end result of this is that when these headers change, we will notice
and rebuild the module.

line arguments and directories tree. The old toolchain selection heuristics
worked incorrectly when user has a reduced MIPS toolchain supports
the O32 ABI only.

Generating RTTI in the MS ABI is currently not supported, and the failures
are confusing to users, so let's disable it by default for now.

Fix an unintentional stdin read in the darwin-asan-nofortify.c test and replace
it with an explicit test for multiple -E inputs passed to the driver.
Noticed while working on the in-process driver patch.

The integrated assembler is a feature. This makes the new flags the default
option, and the previous versions aliases. Ideally, at some point the aliases
would be entirely removed.

In r199283 I switched the name of this variable to CCC_OVERRIDE_OPTIONS, but
I kept some code to continue recognizing the old name temporarily. As far as
I know, the only use of this was for some internal testing at Apple, and we've
now switched to use the new name. If anyone else is still using this and needs
more time to switch names, I guess we'll find out! <rdar://problem/15821425>
