[LLVMdev] All backends now use the MC asm printer

Well, there is still some work to be done before I would call the
transition complete. A big part of the old logic is still present
behind PrintAsmOperand. On targets that have an asm parser (and all of
them should have one at some point), we should be parsing the inline
asm string and then printing the operands as with regular
instructions.
