LowerBitSets: Give names to aliases of unnamed bitset element objects. It is valid for globals to be unnamed, but aliases must have a name. To avoid creating invalid IR, we need to assign names to any aliases we create that point to unnamed objects that have been moved into combined globals. llvm-svn: 239590

LowerBitSets: Do not assign names to aliases of unnamed bitset element objects. The restriction on unnamed aliases was removed in r239921. Mostly reverts r239590, but we keep the test. llvm-svn: 239923
