It's a bit of a tradeoff, since llvm-dwarfdump doesn't print the name of the global symbol being used as an address in the addressing mode, but this avoids the dependence on hardcoded set labels that keep changing (5+ commits over the last few years that each update the set label as it changes due to other, unrelated differences in output). This could've, instead, been changed to match the set name then match the name in the string pool but that would present other issues (needing to skip over the sets that weren't of interest, etc) and checking that the addresses (granted, without relocations applied - so it's not the whole story) match in the two variable location descriptions seems sufficient and fairly stable here. There are a few similar other tests with similar label dependence that I'll update soonish. llvm-svn: 214878
