Don't retry verification at compile time.

We don't re-verify verified or erroneous classes at compile time. We
also need to not re-verify compile time verified classes or else the
class status can become misleading.

This should fix races seen in dalvik-dev builds since parallel
verification was re-enabled.

Some other code and logic clean up.
