304dda7810 Narrow right shifts need to encode their immediates differently from a normal 
shift.

   16-bit: imm6<5:3> = '001', 8 - <imm> is encded in imm6<2:0>
   32-bit: imm6<5:4> = '01',16 - <imm> is encded in imm6<3:0>
   64-bit: imm6<5> = '1', 32 - <imm> is encded in imm6<4:0>

3bc73b0ae9 [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bit 
and 256-bit forms.  Because the number of elements in a vector
      does not determine the vector type (4 elements could be v4f32 or
      v4f64), pass the full type of the vector to decode routines.

The implemented algorithm is overly simplistic (just speculate all branches are
taken)- this is work in progress.

dcc97b5f44 srem doesn't actually have the same resulting sign as its numerator, you could 
also have a zero when numerator = denominator. Reverts parts of r126635 and
r126637.

4026d01040 Add preliminary support for .f32 in the PTX backend. 
- Add appropriate TableGen patterns for fadd, fsub, fmul.
- Add .f32 as the PTX type for the LLVM float type.
- Allow parameters, return values, and global variable declarations
  to accept the float type.
- Add appropriate test cases.

e0f44d0aba The sign of an srem instruction is the sign of its dividend (the first 
argument), regardless of the divisor. Teach instcombine about this and fix
test7 in PR9343!

b35d45a714 Target/X86: Always emit "push/pop GPRs" in prologue/epilogue and emit "spill/reload frames" for XMMs. 
It improves Win64's prologue/epilogue but it would not affect ia32 and amd64 (lack of nonvolatile XMMs).
