This corrects a problem where x86 instructions that implicitly define/use both an A-register (RAX, EAX, ..) and EFLAGS were declared as only defining/using EFLAGS, because the outer "let Defs/Uses = [EFLAGS]" in the various multiclasses overrides the "let Defs/Uses = [areg]" in BinOpAI. The instructions deriving from BinOpAI were moved out of the "let Defs", and a BinOpAI_FF class was created, for instructions that implicitly define and use EFLAGS and the A-register (SBC, ADC). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182883 91177308-0d34-0410-b5e6-96231b3b80d8
