This patch defines a MIR format for debug instruction references: it's an integer trailing an instruction, marked out by "debug-instr-number", much like how "debug-location" identifies the DebugLoc metadata of an instruction. I'm not wed to this name, or particularly to this syntax, but something is needed.

I've added a round-trip test and two verifier checks: that we don't label meta-instructions as generating values, and that there are no duplicates.
