Make mirrors no longer able to create new instances of enum classes.
(If that breaks anyone, they had it coming! It would invalidate
exhaustiveness of switches and thereby soundness in general.)
Also fix a number of failing tests,
delete some no longer relevant tests (e.g. testing
reflection of programs that won't compile, there
are no runtime compilation errors any more.)
Fix some more tests that were failing. Not all.
Tested: Refactoring of existing tests.
