Fix tests: Prevent stack overflow during dtor

On s390x the stack is smaller and/or the object dtor code uses more stack,
which causes the destruction of deeply nested objects to crash in these
tests. Here I ensure that objects are released one by one at the end of the
tests to avoid recursive dtor.

GH-16067: prevent invalid `abstract` during compilation of methods (GH-16069)

For classes that are not declared `abstract`, produce a compiler error for any
`abstract` methods. For anonymous classes, since they cannot be made abstract,
