>Description:
verify.cc:is_assignable_from_slow() is incorrect.
The entire "source->isInterface()" branch is useful
when merging, but otherwise it yields incorrect results.
The fix is to rewrite merging a bit, to rename this
function, and to change one of the calls to a call
to _Jv_isAssignableFrom (which now understands how to
check uninitialized classes).
