Philip Pfaffe b39a97c8f6 [NewPM] Port Msan
Summary:
Keeping msan a function pass requires replacing the module level initialization:
That means, don't define a ctor function which calls __msan_init, instead just
declare the init function at the first access, and add that to the global ctors
list.

Changes:
- Pull the actual sanitizer and the wrapper pass apart.
- Add a newpm msan pass. The function pass inserts calls to runtime
  library functions, for which it inserts declarations as necessary.
- Update tests.

Caveats:
- There is one test that I dropped, because it specifically tested the
  definition of the ctor.

Simon Pilgrim 6199784c5a [X86] Change 'simple nonmem' intrinsic test to not use PADDSW
Those intrinsics will be autoupgraded soon to @llvm.sadd.sat generics (D55894), so to keep a x86-specific case I'm replacing it with @llvm.x86.sse2.pmulhu.w

Chandler Carruth 16429acacb [x86] Revert r330322 (& r330323): Lowering x86 adds/addus/subs/subus intrinsics
The LLVM commit introduces a crash in LLVM's instruction selection.

I filed http://llvm.org/PR37260 with the test case.

Alexander Ivchenko e8fed1546e Lowering x86 adds/addus/subs/subus intrinsics (llvm part)
This is the patch that lowers x86 intrinsics to native IR
in order to enable optimizations. The patch also includes folding
of previously missing saturation patterns so that IR emits the same
machine instructions as the intrinsics.

Craig Topper 2b54baeb96 [X86] Replace 'REQUIRES: x86' in tests with 'REQUIRES: x86-registered-target' which seems to be the correct way to make them run on an x86 build.

Justin Bogner 3a3e115e81 MSan: Mark MemorySanitizer tests that use x86 intrinsics as REQUIRES: x86
Tests that use target intrinsics are inherently target specific. Mark
them as such.
