6211386799 Remove some spurious mayLoad = 0 flags. 
They were inserted to silence TableGen's warning about
redundant properties. That warning is now gone.

674101e6bb [ms-inline asm] Avoid a false positive assertion 
Assertion failed: (Start.isValid() == End.isValid() && "Start and end should 
either both be valid or both be invalid!")

when parsing inline asm.  SMLoc assumes that the first char * in the source is
invalid.  However, when parsing an inline asm the mnemonic is at this location.
I don't want to change SMLoc, so use a trivial workaround.

64bfcbbc58 [ms-inline asm] Expose the ErrorInfo from the MatchInstructionImpl. In general, 
this is the index of the operand that failed to match.

Note: This may cause a buildbot failure due to an API mismatch in clang.  Should
recover with my next commit to clang.

d60cb11afd When unsafe math is used, we can use commutative FMAX and FMIN. In some cases 
this allows for better code generation.

Added a new DAGCombine transformation to convert FMAX and FMIN to FMANC and
FMINC, which are commutative.

For example:

  movaps  %xmm0, %xmm1
  movsd LC(%rip), %xmm0
  minsd %xmm1, %xmm0

becomes:

  minsd LC(%rip), %xmm0

b5838689c6 The X86 backend has a number of optimizations for SETCC nodes which use 
arithmetic instructions. However, when small data types are used, a truncate
node appears between the SETCC node and the arithmetic operation. This patch
adds support for this pattern.

Before:
  xorl  %esi, %edi
  testb %dil, %dil
  setne %al
  ret

After:
  xorb  %dil, %sil

7091b2451d fix PR11334 
- FP_EXTEND only support extending from vectors with matching elements.
  This results in the scalarization of extending to v2f64 from v2f32,
  which will be legalized to v4f32 not matching with v2f64.
- add X86-specific VFPEXT supproting extending from v4f32 to v2f64.
- add BUILD_VECTOR lowering helper to recover back the original
  extending from v4f32 to v2f64.
- test case is enhanced to include different vector width.
