SVN rev 213185 on 2010-09-26 14:20:09Z by nwhitehorn
Check for NULL link registers as found in initial stack frames when doing
stack unwinding, instead of naively trying to check the instruction at
that location. This fixes signal handling in threaded applications after
recent changes regarding unwinding in libthr. While here, clean up our
MD_FROB_UPDATE_CONTEXT() implementation a little.
