f68fc742 - New semantic analyzer: fix ambiguity between submodule and local definition (#7017)

New semantic analyzer: fix ambiguity between submodule and local definition (#7017) Now imports are biased to target the submodule of current package target, but elsewhere a local definition with the same name as a submodule takes precedence. Even though this doesn't quite reflect what happens at runtime, this seems to cover the typical use cases well, and the implementation is simple. Fixes #6828.
