Do not place null check from unresolved field access.
Rationale:
These accesses go though the runtime anyway where various
checks are done, including null check. Since particular
checks, like access checks, need to occur prior to the
null check (to ensure link errors are not masked by
a null reference), the explicit null check should not
occur in the HIR.

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.
