Bug #35137
* unwind.c (uw_unwind_to_exit_point): When jumping to a catch frame,
do not mark it invisible.
* unwind.h (uw_catch): Flip the matches to nil so that this catch
frame can no longer be identified as an unwind point by uw_throw,
and thus will not be re-entered for the purposes of handling
an exception. It remains visible for the purposes of running the
clean up code.
(uw_unwind): Prior to executing cleanup forms, flip the visibility
to 0. This means that the frame will no longer be re-entered
for any reason.
