Quentin Colombet 6f12ae0d5c [X86] Add broadcast instructions to the table used by ExeDepsFix pass. 
Adds the different broadcast instructions to the ReplaceableInstrsAVX2 table.
That way the ExeDepsFix pass can take better decisions when AVX2 broadcasts are
across domain (int <-> float).

In particular, prior to this patch we were generating:
  vpbroadcastd  LCPI1_0(%rip), %ymm2
  vpand %ymm2, %ymm0, %ymm0
  vmaxps  %ymm1, %ymm0, %ymm0 ## <- domain change penalty

Now, we generate the following nice sequence where everything is in the float
domain:
  vbroadcastss  LCPI1_0(%rip), %ymm2
  vandps  %ymm2, %ymm0, %ymm0
  vmaxps  %ymm1, %ymm0, %ymm0

Manman Ren 98a5bf24a9 X86: add more GATHER intrinsics in LLVM 
Corrected type for index of llvm.x86.avx2.gather.d.pd.256
  from 256-bit to 128-bit.
Corrected types for src|dst|mask of llvm.x86.avx2.gather.q.ps.256
  from 256-bit to 128-bit.

Support the following intrinsics:
  llvm.x86.avx2.gather.d.q, llvm.x86.avx2.gather.q.q
  llvm.x86.avx2.gather.d.q.256, llvm.x86.avx2.gather.q.q.256
  llvm.x86.avx2.gather.d.d, llvm.x86.avx2.gather.q.d
  llvm.x86.avx2.gather.d.d.256, llvm.x86.avx2.gather.q.d.256
