Craig Topper b2a626b52e [X86] Remove the max vector width restriction from combineLoopMAddPattern and rely splitOpsAndApply to handle splitting. 
This seems to be a net improvement. There's still an issue under avx512f where we have a 512-bit vpaddd, but not vpmaddwd so we end up doing two 256-bit vpmaddwds and inserting the results before a 512-bit vpaddd. It might be better to do two 512-bits paddds with zeros in the upper half. Same number of instructions, but breaks a dependency.
