Push a scope_stack entry for match_first blocks, and handle impls being inside those scope entries. An impl should not use the `match_first` block as its "enclosing scope" for the purpose of deciding if the impl is a redecl of another impl. We should look through it to the class or namespace the impl (and match_first) are located inside. We don't yet store the relationship between the impl and its match_first block, nor then can we use it in impl lookup for prioritization.
