aarch64: Use VNx16BI for floating-point svcmp*

This patch continues the work of making ACLE intrinsics use VNx16BI for svbool_t results. It deals with the floating-point forms of svcmp*. gcc/ * config/aarch64/aarch64-sve.md (@aarch64_pred_fcm<cmp_op><mode>_acle) (*aarch64_pred_fcm<cmp_op><mode>_acle, @aarch64_pred_fcmuo<mode>_acle) (*aarch64_pred_fcmuo<mode>_acle): New patterns. * config/aarch64/aarch64-sve-builtins-base.cc (svcmp_impl::expand, svcmpuo_impl::expand): Use them. gcc/testsuite/ * gcc.target/aarch64/sve/acle/general/cmpeq_6.c: New test. * gcc.target/aarch64/sve/acle/general/cmpge_9.c: Likewise. * gcc.target/aarch64/sve/acle/general/cmpgt_9.c: Likewise. * gcc.target/aarch64/sve/acle/general/cmple_9.c: Likewise. * gcc.target/aarch64/sve/acle/general/cmplt_9.c: Likewise. * gcc.target/aarch64/sve/acle/general/cmpne_5.c: Likewise. * gcc.target/aarch64/sve/acle/general/cmpuo_1.c: Likewise.
