Fix a bug in abrupt exit from with or catch inside finally.

Fix a bug in abrupt exit from with or catch inside finally.

When with or catch is nested inside finally, we were not properly restoring
the context in the stack for the finally code.  Also, as a small
optimization, restore it from the handler block instead of iteratively
unwinding contexts.
