Add 'isCodeGenOnly' bit to Instruction .td records.
- Used to mark fake instructions which don't correspond to an actual machine
instruction (or are duplicates of a real instruction). This is to be used for
"special cases" in the .td files, which should be ignored by things like the
assembler and disassembler. We still need a good solution to handle pervasive
duplication, like with the Int_ instructions.
- Set the bit on fake "mov 0" style instructions, which allows turning an
assembler matcher warning into a hard error.
- -2 FIXMEs.
