Esteban Küber 7dffd24da5 Tweak privacy errors to account for reachable items
Suggest publicly accessible paths for items in private mod:

  When encountering a path in non-import situations that are not reachable
  due to privacy constraints, search for any public re-exports that the
  user could use instead.

Track whether an import suggestion is offering a re-export.

When encountering a path with private segments, mention if the item at
the final path segment is not publicly accessible at all.

Add item visibility metadata to privacy errors from imports:

  On unreachable imports, record the item that was being imported in order
  to suggest publicly available re-exports or to be explicit that the item
  is not available publicly from any path.

  In order to allow this, we add a mode to `resolve_path` that will not
  add new privacy errors, nor return early if it encounters one. This way
  we can get the `Res` corresponding to the final item in the import,
  which is used in the privacy error machinery.

A variety of tests around reachability. These tests in general check two things:

  • that we get unreachable code warnings in reasonable locations;
  • that we permit coercions into ! from expressions which diverge, where an expression "diverges" if it must execute some subexpression of type !, or it has type ! itself.
