Reuse the selection code from the ld2 case. This is similar to how SDAG handles things in AArch64ISelDAGToDAG. (See `SelectLoad`)

This fell back ~100 times while building clang with GISel enabled for AArch64.

Factoring out the gross subreg copy part ought to make selecting the rest of this family fairly easy.
