aarch64: Use VNx16BI for svdupq_b*

This patch continues the work of making ACLE intrinsics use VNx16BI
for svbool_t results.  It deals with the predicate forms of svdupq.

The general predicate expansion builds an equivalent integer vector
and then compares it with zero.  This patch therefore relies on
the earlier patches to the comparison patterns.

gcc/
	* config/aarch64/aarch64-protos.h
	(aarch64_convert_sve_data_to_pred): Remove the mode argument.
	* config/aarch64/aarch64.cc
	(aarch64_sve_emit_int_cmp): Allow PRED_MODE to be VNx16BI or
	the natural predicate mode for the data mode.
	(aarch64_convert_sve_data_to_pred): Remove the mode argument
	and instead always create a VNx16BI result.
	(aarch64_expand_sve_const_pred): Update call accordingly.
	* config/aarch64/aarch64-sve-builtins-base.cc
	(svdupq_impl::expand): Likewise, ensuring that the result
	has mode VNx16BI.

gcc/testsuite/
	* gcc.target/aarch64/sve/acle/general/dupq_13.c: New test.
