aarch64: Use memcpy to copy vector tables in vst2[q] intrinsics
Use __builtin_memcpy to copy vector structures instead of building
a new opaque structure one vector at a time in each of the vst2[q]
Neon intrinsics in arm_neon.h. This simplifies the header file and
also improves code generation - superfluous move instructions were
emitted for every register extraction/set in this additional
structure.
Add new code generation tests to verify that superfluous move
instructions are no longer generated for the vst2q intrinsics.
