This was coming in weird debug info that had variables (and hence debug_locs) but was in GMLT mode (because it was missing the 13th field of the compile_unit metadata) so no ranges were constructed. We should always have at least one range for any CU with a debug_loc in it - because the range should cover the debug_loc. The assertion just ensures that the "!= 1" range case inside the subsequent loop doesn't get entered for the case where there are no ranges at all, which should never reach here in the first place. llvm-svn: 214939
