1268 The strategy we now use is to pre allocate the top_elt along
1269 with the EH context so that each thread has its own top_elt.

3414 Don't clear after_call for a CLOBBER.
3415 Keep track of how many hard registers need to be copied from
3416 after_call, and don't clear after_call before we have seen
