[X86] Don't emit X86::MOV8rr_NOREX from X86InstrInfo::copyPhysReg. This hook is called after register allocation with two physical registers. We don't need a separate instruction at that time to force register class constraints. I left in the assert though. We also have a fatal error in X86MCCodeEmitter if we ever encode an H-reg and a REX prefix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@314248 91177308-0d34-0410-b5e6-96231b3b80d8
