Do more inlining when JITting.

We now check the verification status of the class.

This triggered a bug when an inlined method was not compiled
(typically in a JIT configuration), and the path for deopting in
StackVisitor was using the wrong ArtMethod in order to know the
compiler that compiled the current frame.
