This is a big redesign of failure-stack and register handling, prompted
by bugs revealed when trying to add shy-groups. Overall, what happened
is that loops are now structured a little differently, groups can be
shy and the code is a little simpler.

push_dummy_failure and dumy_failure_jump.
Add on_failure_jump_(exclusive, loop and smart).
Also fix the comment for (start|stop)_memory since they now only take
one argument (the second has becomes unnecessary).

of on_failure_jump_loop for greedy loops.
Add code for the new on_failure_jump_<foo>.
Remove ad-hoc code in `on_failure_jump' to push more registers
