With the recent update to setjmp, we now need to restore the hard frame pointer
directly from the saved frame pointer. We don't need to adjust for the offset
between
the virtual_stack_vars_rtx and the hard frame pointer.
Tested on hppa-unknwon-linux-gnu, hppa2.0w-hp-hpux11.11 and hppa64-hp-hpux11.11.
Committed to trunk.
