Switch to libcorkscrew for native stack traces.

This is both for the current thread (which backtrace(3) could do) and other
threads, which is functionality we didn't have on x86 before.
We jump through the appropriate hoops to get static symbols as well as dynamic
ones.

Also unify the existing native stack dumpers so they can share the best code.

Example x86 check failure:

  *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
  Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR) fault addr 0xdeadd00d
  Registers:
