aarch64: Use the correct GP mode in the svcmp_wide patterns
The patterns for the svcmp_wide intrinsics used a VNx16BI
input predicate for all modes, instead of the usual <VPRED>.
That unnecessarily made some input bits significant, but more
importantly, it triggered an ICE in aarch64_sve_same_pred_for_ptest_p
when testing whether a comparison pattern could be fused with a PTEST.
A later patch will add tests for other comparisons.
gcc/
* config/aarch64/aarch64-sve.md (@aarch64_pred_cmp<cmp_op><mode>_wide)
(*aarch64_pred_cmp<cmp_op><mode>_wide_cc): Use <VPRED> instead of
VNx16BI for the governing predicate.
(*aarch64_pred_cmp<cmp_op><mode>_wide_ptest): Likewise.
gcc/testsuite/
* gcc.target/aarch64/sve/acle/general/cmpeq_1.c: Add more tests.
