aarch64: Fix gcs save/restore_stack_nonlocal
The save/restore_stack_nonlocal patterns passed a DImode rtx to
gen_tbranch_neqi3 for a QImode compare. But since we're seeding
r16 with 1, GCSEnabled will clear the only set bit in r16, so we
can use CBNZ instead of TBNZ.
gcc:
* config/aarch64/aarch64.md (tbranch_<EQL><SHORT>3): Remove.
(save_stack_nonlocal): Use aarch64_gen_compare_zero_and_branch.
(restore_stack_nonlocal): Likewise.
gcc/testsuite:
* gcc.target/aarch64/gcs-nonlocal-3.c: Match cbnz.
