Note that __sigsetjmp() did NOT flush the register stack. Instead,
we do it here since __longjmp() is usually much less frequently
invoked than __sigsetjmp(). The only difficulty is that __sigsetjmp()
didn't (and wouldn't be able to) save ar.rnat either. This is a problem
because if we're not careful, we could end up loading random NaT bits.
There are two cases:
(i) ar.bsp < ia64_rse_rnat_addr(jmpbuf.ar_bsp)
ar.rnat contains the desired bits---preserve ar.rnat
across loadrs and write to ar.bspstore
(ii) ar.bsp >= ia64_rse_rnat_addr(jmpbuf.ar_bsp)
The desired ar.rnat is stored in
ia64_rse_rnat_addr(jmpbuf.ar_bsp). Load those
bits into ar.rnat after setting ar.bspstore. */
