The signal context structure pointer is always saved at the base

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.
The kernel apparently sets %r31 in the saved state structure to point
to the active instruction when the signal was taken. Everything
else looks fairly reasonable. (I assume the kernel fixes %r31 from
within _sigreturn?. */
