hppa: Don't clobber frame_pointer_rtx in expanders

Noticed testing LRA.  Clobbers cause internal compiler errors.

2024-10-05  John David Anglin  <dang...@gcc.gnu.org>

gcc/ChangeLog:

        * config/pa/pa.md (nonlocal_goto): Don't clobber
        frame_pointer_rtx.
        (builtin_longjmp): Likewise.
