Created an attachment (id=135495)
 --> (https://bugs.webkit.org/attachment.cgi?id=135495&action=review)
the patch

The previous patch failed to save/restore the correct state for finally inlining.  For example:

try {
   switch (foo) {
   case blah:
      return bar;
   }
} finally {
    break;
}

Since the finally block was emitted inline in the return, the break would break us out of the switch.

Other similarly horrible things would happen with scope depth and the finally depth, etc.
