Teach stackinfo::walk() how to virtually unwind the tls sigstack
This improves how stackinfo::dumpstack() dumps _sigbe and sigdelayed frames
* exceptions.cc (stack_info): Add sigstackptr member.
(walk): Unwind sigstackptr inside _sigbe and sigdelayed.
* gendef (_sigdelayed_end): Add symbol to mark end of sigdelayed.
