the hardware save state structure, which lives 10 32bit words into
sigcontext structure.
Within the hardware save state structure, registers are found in the
same order as the register numbers in GDB.
At one time we peeked at %r31 rather than the PC queues to determine
what instruction took the fault. This was done on purpose, but I don't
remember why. Looking at the PC queues is really the right way, and
I don't remember why that didn't work when this code was originally
written. */
