The recent change in the delegate semantics was incorrectly implemented
in the interpreter. It only checked that the first opcode of the target
block is a 'try': we also need to skip try blocks when we are already in
their 'catch' or 'catch_all' sub-block.
Use the exception_stack instead, since it already only contains indices
of try blocks that haven't reached their handlers yet.
