Asumu Takikawa 9b4e3befa3 Remove the depth subtype check on #:implements
This check was not really necessary to begin with,
but I thought it might be a useful sanity check. In
retrospect, calling `subtype` here causes other headaches
(such as when registering type aliases) and is confusing
when multiple #:implements are provided.

Instead, the #:implements clauses are just linearized
and the last type for any given method/field is taken.

This may also prevent a heisenbug that occurs in the
GUI framework types. I still don't know the root cause of
that non-determinism though.
