Alpha: Restore frame pointer last in `builtin_longjmp' [PR64242]
Add similar arrangements to `builtin_longjmp' for Alpha as with commit
71b144289c1c ("re PR middle-end/64242 (Longjmp expansion incorrect)")
and commit 511ed59d0b04 ("Fix PR64242 - Longjmp expansion incorrect"),
so as to restore the frame pointer last, so that accesses to a local
buffer supplied can still be fulfilled with memory accesses via the
original frame pointer, fixing:
FAIL: gcc.c-torture/execute/pr64242.c -O0 execution test
FAIL: gcc.c-torture/execute/pr64242.c -O1 execution test
FAIL: gcc.c-torture/execute/pr64242.c -O2 execution test
FAIL: gcc.c-torture/execute/pr64242.c -O3 -g execution test

FAIL: gcc.c-torture/execute/pr64242.c -O2 -flto -fno-use-linker-plugin -flto-partition=none execution test
FAIL: gcc.c-torture/execute/pr64242.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects execution test
and adding no regressions in `alpha-linux-gnu' testing.
