Tim Northover b62ba5eca0 AArch64/ARM64: implement BFI optimisation 
ARM64 was not producing pure BFI instructions for bitfield insertion
operations, unlike AArch64. The approach had to be a little different (in
ISelDAGToDAG rather than ISelLowering), and the outcomes aren't identical but
hopefully this gives it similar power.

This should address PR19424.
