5ac1e8e6b1 Begin fixing Clang's predefined macros for various architectures. This 
is *very* much a WIP that I'll be refining over the next several
commits, but I need to get this checkpoint in place for sanity.

This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.

0706d203cf Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. 
Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag.

79a91418bd Switch LangOptions over to a .def file that describes header of the 
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.

69a990badb Clang/PNaCl: Improve test coverage for PNaClTargetInfo (type aligns), fixes nits: 
- wrong alignment for double (it was 4, but 8 is desired),
- added checks for _REENTRANT define,
- fixed the issue that defines were not tested (because the check for inside #ifdef).

18903ee2d3 Add partial support for using anonymous bitfields (e.g., int : 0) to enforce 
alignment.  This fixes cases where the anonymous bitfield is followed by a 
non-bitfield member.  E.g.,

struct t4
{
  int foo : 1;
  long : 0;
  char bar;
};

3472838c7a Disable avx feature from corei7-avx, and use -mavx for now. Right now, if -mavx is 
specified, 128 avx code is used and we're not sure yet if this the behavior
we want (and if it does, some improvements are needed before relying on it).

3346582bca Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx should not imply -mno-sse. 
Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__.

clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much.

491f56d41e Fix a FIXME in clang ARM driver that was exposed as a bug with ARM backend 
change.

Previously clang was passing the following feature strings to the ARM backend
when CPU is cortex-a8: +neon,-vfp2,-vfp3

This used to work because -vfp2,-vfp3 had no effect after +neon. Now that the
features are controlled by individual bits (with implied hierarchy), the net
effect is all three features will be turned off.
