have the mc lowering process handle a few tail call forms, lowering them to
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.
This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.
However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.
