  Changed paths:
    M llvm/lib/Target/X86/X86ISelLowering.cpp
    M llvm/test/CodeGen/X86/mmx-cvt.ll

  Log Message:
  -----------
  [X86] Fold (v2i64 (scalar_to_vector (i64 (bitcast (double))))) -> (bitcast (v2f64 scalar_to_vector))

This can occur more frequently after the MMX retirement if anyone is still using MMX intrinsics that now wrap to SSE
