Sterling Augustine 71fbd6e406 Exit unwinding early when at the top of the stack and additional info won't be found. 
Summary:
This patch follows libgcc's lead: When the return-address register is
zero, there won't be additional stack frames to examine, or gather
information about. Exit before spending time looking for something
known not to be found.
