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.

Phabricator code review is located here: http://llvm-reviews.chandlerc.com/D1693

Ben Langmuir 58078d0103 Add C intrinsics for Intel SHA Extensions 
Intrinsics added shaintrin.h, which is included from x86intrin.h if __SHA__ is
enabled. SHA implies SSE2, which is needed for the __m128i type.

Also add the -msha/-mno-sha option.

Craig Topper c0070a4320 Fix a bug where -msse followed by -mno-sse would leave MMX enabled.

Craig Topper 7481d8aa17 Separate popcnt and sse4.2 feature control somewhat to match gcc behavior. 
Enabling sse4.2 will implicitly enable popcnt unless popcnt is explicitly disabled.
Disabling sse4.2 will not disable popcnt if popcnt is explicitly enabled.

Rafael Espindola 0221d8636e Don't disable SSE4A when disabling AVX. 
Thanks for Craig Topper for noticing it.

Rafael Espindola db0fcfbfae Centralize the logic for handling -m* options and fix pr16943. 
This moves the logic for handling -mfoo -mno-foo from the driver to -cc1. It
also changes -cc1 to apply the options in order, fixing pr16943.

The handling of -mno-mmx -msse is now an explicit special case.

Daniel Dunbar 5618e98f33 Update tests to use %clang instead of 'clang', and forcibly disable use of ' 
clang ' or ' clang -cc1 ' or ' clang-cc ' in test lines (by substituting them to
garbage).

Daniel Dunbar 8b57697954 Eliminate &&s in tests. 
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Daniel Dunbar f9d90275f9 Handle -march for the LLVM recognized cpu names. 
- x86 target feature handling should not be feature complete, even if
   the code quality is lacking.

Daniel Dunbar bb36aed06b More x86 target feature support. 
- Apologies for the extremely gross code duplication, I want to get
   this working and then decide how to get this information out of the
   back end.

 - This replaces -m[no-]sse4[12] by -m[no-]sse4, it appears gcc
   doesn't distinguish them?

 - -msse, etc. now properly disable/enable related features.

 - Don't always define __SSE3__...

 - The main missing functionality bit here is that we don't initialize
   the features based on the CPU for all -march options.
