I don't think the backend is the correct place to handle this. If we
do need to print assembly without .loc, I think the asm streamer is
the correct place to isolate the problem. The idea is

* EmitDwarfLocDirective prints nothing
* Finish prints a debug_lines section using DW_LNE_set_address.

IMHO it would be better for llvm-gcc to use llvm-mc, but if that is
not possible for some reason I can extend the MC asm printer.
