This patch extends
function_expander::use_contiguous_load_insn and
function_expander::use_contiguous_store_insn functions to
support predicated versions.

	* config/arm/arm-mve-builtins.cc
	(function_expander::use_contiguous_load_insn): Add support for
	PRED_z.
	(function_expander::use_contiguous_store_insn): Add support for
	PRED_p.
