commit r12-2782-g1deb0818f4bca408994f666c1bd43289753507f5

aarch64: Use memcpy to copy structures in vst2[q]_lane intrinsics
Use __builtin_memcpy to copy vector structures instead of using a
union - or constructing a new opaque structure one vector at a time -
in each of the vst2[q]_lane Neon intrinsics in arm_neon.h.
Add new code generation tests to verify that superfluous move
instructions are not generated for the vst2q_lane intrinsics.
