The MONITOR and MWAIT instructions have insufficient information for decoding. Essentially, they both map to the same column in the "opcode extensions for one- and two-byte opcodes" table in the x86 manual. The RawFrm complicates decoding this. Instead, use opcode 0x01, prefix 0x01, and form MRM1r. Then have the code emitter special case these, a la [SML]FENCE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72556 91177308-0d34-0410-b5e6-96231b3b80d8
