X86 was already specially marking fma as commutable which allowed tablegen to autogenerate commuted patterns. This moves it to the target independent definition and fix up the targets to remove now unneeded patterns. Unfortunately, the tests change because the commuted version of the patterns are generating operands in a different than the explicit patterns. Differential Revision: https://reviews.llvm.org/D91842
