2018-09-03py/vm: Fix handling of finally-return with complex nested finallys.Damien George
Back in 8047340d7532ec32bc9f2d603bffc0bc9544297f basic support was added in the VM to handle return statements within a finally block. But it didn't cover all cases, in particular when some finally's were active and others inactive when the "return" was executed. This patch adds further support for return-within-finally by correctly managing the currently_in_except_block flag, and should fix all cases. The main point is that finally handlers remain on the exception stack even if they are active (currently being executed), and the unwind return code should only execute those finally's which are inactive. New tests are added for the cases which now pass.
