Benjamin Kramer d9a5e2a490 Driver: Add support for -march=bdver3 on x86.

Eric Christopher 2fe3b4a490 Add preprocessor support for powerpc vsx. 
The test should be expanded upon for more powerpc checking.

Eric Christopher c26a5b4f9d Remove an old, seemingly out of date, comment. 
The referenced script no longer seems to exist.

Yunzhong Gao 6108936fa6 Enabling 3DNow! prefetch instruction support for a few AMD processors in the 
clang front end. This change will allow the __PRFCHW__ macro to be set on these
processors and hence include prfchwintrin.h in x86intrin.h header. Support for
the intrinsic itself seems to have already been added in r178041.

Yunzhong Gao 1f6aeebe76 Adding -mtbm and -mno-tbm command line options to the clang front end for the 
x86 TBM instruction set. Also adding a __TBM__ macro if the TBM feature is
enabled. Otherwise there should be no functionality change to existing features.

Rafael Espindola 925213b0fa Add 'not' to commands that are expected to fail. 
This is at least good documentation, but also opens the possibility of
using pipefail.

Michael Liao 625a875f05 Add clang support of RTM from TSX 
- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature
- Builtin macro '__RTM__' is defined if RTM feature is enabled
- RTM intrinsic header is added and introduces 3 new intrinsics, namely
  '_xbegin', '_xend', and '_xabort'.
- 3 new builtins are added to keep compatible with gcc, namely
  '__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'.
- Test cases for pre-defined macro and new intrinsic codegen are added.

Benjamin Kramer 1e250395fa Wire up -mrdrnd for X86. 
For some reason GCC decided to call the feature rdrnd instead of rdrand,
which requires translating it for LLVM.

Benjamin Kramer 8ac9c22391 Define __SSE4A__ when targeting new AMD CPUs. 
This doesn't really fit the existing SSELevel so it gets an extra flag.

Simon Atanasyan ce005eb2c6 Pass a target triple explicitly to check platform specific macros definitions. 
That allows to run the tests on all platforms successfully.

Chandler Carruth cd99bad4ac Generate tests for all of the x86 SIMD instruction feature set 
predefines based on the output of GCC as well as the CPU predefines.

Invert tests for __AVX__, Clang's AVX feature is hard coded off still.

Switch Atom from 'SSE3' to 'SSSE3'. This matches GCC's behavior, Intel's
documentation, and ICC's documentation (such as I could dig up).

Switch Athlon and Geode to enable 3dnowa rather than just 3dnow and
nothing (resp.).

Chandler Carruth e83c3d9d33 Add a little banner to this test. This lets my scripts more easily 
automate the process of updating and generating these tests.

If anyone is really interested, I can check my scripts for generating
this test in, but its a horrible pile of shell... Not sure its really
worth it.

__tune_...__ define as well.

Chandler Carruth 6e20c2bd35 Teach Clang to reject 32-bit only CPUs when compiling in 64-bit mode. 
Add 64-bit preprocessor macro tests.

Chandler Carruth 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.
