rip out the 'heinous' x86 MCCodeEmitter implementation. We still have the templated X86 JIT emitter, *and* the almost-copy in X86InstrInfo for getting instruction sizes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96059 91177308-0d34-0410-b5e6-96231b3b80d8

fix the encodings of monitor and mwait, which were completely busted in both encoders. I'm not bothering to fix it in the old one at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95947 91177308-0d34-0410-b5e6-96231b3b80d8

Define the x86 pause instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104204 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the sfence instruction to use MRM_F8 instead of MRM7r, since it doesn't have a register operand. Also, use I instead of PSI, for consistency with mfence and lfence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104203 91177308-0d34-0410-b5e6-96231b3b80d8

MC/AsmParser: Attempt to constant fold expressions up-front. This ensures we avoid fixups for obvious cases like '-(16)'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96064 91177308-0d34-0410-b5e6-96231b3b80d8
