arm: Auto-vectorization for MVE clean condition for vand and vorr expanders

The patch restores the unconditional definition of the VDQ iterator,
and changes the conditions of the vand and vorr expanders to use
ARM_HAVE_<MODE>_ARITH.

2020-12-11  Christophe Lyon  <christophe.lyon@linaro.org>

	gcc/
	* config/arm/iterators.md (VDQ): Remove TARGET_HAVE_MVE
	conditions.
	* config/arm/vec-common.md (and<mode>3): Use
	ARM_HAVE_<MODE>_ARITH.
	(ior<mode>3): Likewise.
