Benjamin Kramer b289319fb8 X86: cvtpi2ps is just an SSE instruction with MMX operands. It has no AVX equivalent. 
Give it the right register format so we can also emit it when AVX is enabled.

We used to generate a store (movq) + a load.
Now we use movd.

Craig Topper 744f6311d3 Don't disable MMX support when AVX is enabled. Fix predicates for MMX instructions that were added along with SSE instructions to check for AVX in addition to SSE level.

Bill Wendling 5d9089ae14 Add test to make sure that the MMX intrinsic calls make it out the other end in 
tact.
