Simon Pilgrim 8893bd95f0 [X86][SSE] Consistently set MOVD/MOVQ load/store/move instructions to integer domain
We are being inconsistent with these instructions (and all their variants.....) with a random mix of them using the default float domain.

Elena Demikhovsky 542dfcf44c Optimized instruction sequence for sitofp operation on X86-32
Optimized sitofp i64 %x to double. The current sequence

movl %ecx, 8(%esp) 
movl %edx, 12(%esp) 
fildll 8(%esp)

is replaced with:

movd %ecx, %xmm0 
movd %edx, %xmm1 
punpckldq %xmm1, %xmm0 
movq %xmm0, 8(%esp)

Michael Kuperstein 58e86bc893 [X86] Fix sitofp and uitofp instruction matching failures with long double and avx512
The operation action for i32 and i64 cannot be set to legal, as long double 
needs custom lowering.
