[LLVMdev] Execution domain for VEXTRACTF128/VINSERTF128

What domain do you think they should have? They are floating point, but not
technically double or single. The domain fix pass will treat them as either
anyway as I've put them in the table for both single and double.

>From X86InstrInfo.cpp

  { X86::VEXTRACTF128mr, X86::VEXTRACTF128mr, X86::VEXTRACTI128mr },
  { X86::VEXTRACTF128rr, X86::VEXTRACTF128rr, X86::VEXTRACTI128rr },
  { X86::VINSERTF128rm,  X86::VINSERTF128rm,  X86::VINSERTI128rm },
  { X86::VINSERTF128rr,  X86::VINSERTF128rr,  X86::VINSERTI128rr },
  { X86::VPERM2F128rm,   X86::VPERM2F128rm,   X86::VPERM2I128rm },
  { X86::VPERM2F128rr,   X86::VPERM2F128rr,   X86::VPERM2I128rr }
