target/arm: Convert Neon VSWP to decodetree
Convert the Neon VSWP insn to decodetree. Since the new implementation doesn't have to share a pass-loop with the other 2-reg-misc operations we can implement the swap with 64-bit accesses rather than 32-bits (which brings us into line with the pseudocode and is more efficient).
