Adding another CU-wide list, in this case of imported_modules (since they should be relatively rare, it seemed better to add a list where each element had a "context" value, rather than add a (usually empty) list to every scope). This takes care of DW_TAG_imported_module, but to fully address PR14606 we'll need to expand this to cover DW_TAG_imported_declaration too. llvm-svn: 179836
