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

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

X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same instruction, we only want to allow the one for the current subtarget. - This also fixes suffix matching for jmp instructions, because it eliminates the ambiguity between 'jmpl' and 'jmpq'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108746 91177308-0d34-0410-b5e6-96231b3b80d8
