I'd have thought AsmPrinter would deal with this, I remember adding code to look at the sequence of emitted .loc directives and handle line 0 specially.  But if this is helping, it seems reasonable.  It would be nice to experiment with actually debugging the generated code and see if the quality of the debugging experience is better/worse/unchanged.  Maybe @jmorse your team can take a quick look?
