[PATCH] D49426: [DEBUG_INFO] fix .loc directives emitted for missing prologues

I wonder if we should experiment with making the line-table builder complain about a .loc that doesn't increment the address.  That would tell us whether these zero-length cases show up anywhere else.  Or, if we decide the assembler should handle it correctly, whether anything slips through.
