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

Changed the encoding of X86 floating point stack operations where both operands are st(0). These can be encoded using an opcode for storing in st(0) or using an opcode for storing in st(i), where i can also be 0. To allow testing with the darwin assembler and get a matching binary the opcode for storing in st(0) is now used. To do this the same logical trick is use from the darwin assembler in converting things like this: fmul %st(0), %st into this: fmul %st(0) by looking for the second operand being X86::ST0 for specific floating point mnemonics then removing the second X86::ST0 operand. This also has the add benefit to allow things like: fmul %st(1), %st that llvm-mc did not assemble. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104634 91177308-0d34-0410-b5e6-96231b3b80d8
