Suppress NO_DEFAULT_BOUND errors.

This suppresses the emission of NO_DEFAULT_BOUND errors, and makes the
default instantation for recursive bounds backwards (and possibly
forwards) compatible.  Also adds a couple of currently failing tests
for cases that should be made erroneous regardless of whether we
choose to support malbounded type constructor applications.
