aarch64: Use memcpy to copy vector tables in vst1[q]_x4 intrinsics
Use __builtin_memcpy to copy vector structures instead of using a
union in each of the vst1[q]_x4 Neon intrinsics in arm_neon.h.
Add new code generation tests to verify that superfluous move
instructions are not generated for the vst1q_x4 intrinsics.
