Reapply "Lazy deopt without code patching."

When throwing to a frame scheduled for lazy deopt, update the continuation pc for that frame to be the catch handler.

Weaken new assert that the deopt pc belongs to the frame's code as the deopt pc for the last eager deopt in a function lies outside the code, after the call to the deopt stub.
