re PR testsuite/78421 (vect-strided-a-u8-i2-gap.c fails on armeb)

	PR testsuite/78421
	* lib/target-supports.exp (check_effective_target_vect_hw_misalign):
	If the target is ARM return the result of the
	check_effective_target_arm_vect_no_misalign proc.
	* gcc.dg/vect/vect-strided-a-u8-i2-gap.c: If the target does not
	support unaligned vectors then only expect one of the loops to be
	unrolled.
