Fix bug in verifier: soft fail was hiding hard fail.

Rationale:
Dexfuzzing found a situation where a soft fail (modifying
a final field) was hiding a hard fail (type error on that
field), which caused a crash in the compiler later on.
Also added a crash-before/pass-after regression test,
so we don't add the return by accident later.
