Not sure if that's a problem or not; and I'm not sure how the conversion has been dealing with this so far. I just wonder whether we should keep the mix ordering and then let the LLVM IR side to fold it into fma if desired.

CL.mix explicitly permits FMA contractions, but GL.FMix does not have the statements. The patterns were splited
