Rather than deferring to the heavyweight validateDeclForNameLookup() to perform the “get overridden decls” operation, perform a much more minimal validation that only looks for exact matches when the ‘override’ modifier is present. The more-extensive checking (e.g., that one didn’t forget an override modifier) is only performed as part of the “full” type checking of a declaration, which will typically only be done within the same source file as the declaration. The intent here is to reduce the amount of work performed to check overrides cross-file, and limit the dependencies of the “get overridden decls” operation.
