[PATCH][AArch64] Fix generation of tst (PR87763)
The TST instruction no longer matches in all cases due to changes in
Combine. The fix is simple, we now need to allow a subreg as well when
selecting the cc_mode. This fixes the tst_5.c and tst_6.c failures.
AArch64 regress & bootstrap OK.
PR rtl-optimization/87763
* config/aarch64/aarch64.c (aarch64_select_cc_mode):
Allow SUBREG when matching CC_NZmode compare.
