Add some extra debugging/diagnostic support.

CHECK that we don't bring a class back from a "permanent" error status in the
oat file at runtime.

CHECK that doesn't hand out 0 as an address for its caller
to branch to.

Also remove some accidentally left in debugging output.

Also fix a few comment typos.
