aarch64: Use VNx16BI for svcmp*_wide

aarch64: Use VNx16BI for svcmp*_wide

This patch continues the work of making ACLE intrinsics use VNx16BI
for svbool_t results.  It deals with the svcmp*_wide intrinsics.

Since the only uses of these patterns are for ACLE intrinsics,
there didn't seem much point adding an "_acle" suffix.

	* config/aarch64/aarch64-sve.md (@aarch64_pred_cmp<cmp_op><mode>_wide):
	Split into VNx16QI_ONLY and SVE_FULL_HSI patterns.  Use VNx16BI
	results for both.
	(*aarch64_pred_cmp<cmp_op><mode>_wide): New pattern.
	(*aarch64_pred_cmp<cmp_op><mode>_wide_cc): Likewise.
