So implement asm-goto already, and do asm-cc-output while you're at it.

The whole asm-goto/jump_label stuff really does make a measureable
difference in performance, and its bloody rediculous LLVM doesn't have
it.

And no, a different interface to do something similar is not OK. We're
not going to have a second implementation of jump-labels and everything
else that uses it.
