Paul Berry b1a54154f8 Check that implicit type arguments satisfy bounds.
This required adding an implementation of super-bounded types to the
analyzer.

We really could use some more tests to verify that we disallow
super-bounded types in all the appropriate locations, but allow it in
other cases (it seems that there are no language_2 tests to verify
this).  To avoid churn, I'll wait until I have confirmation that my
reasoning is correct in #34583 before submitting test cases.

Fixes #34532.
Fixes #34560.
