RFC https://discourse.llvm.org/t/rfc-dwarfdebug-fix-and-improve-handling-imported-entities-types-and-static-local-in-subprogram-and-lexical-block-scopes/68544 Currently, `retainedNodes` tracks function-local variables and labels. To support function-local import, types and static variables (which are globals in LLVM IR), subsequent patches use the same field. So this patch makes preliminary refactoring of the code tracking local entities to apply future functional changes lucidly and cleanly. No functional changes intended.
