Peter Maydell d25998ba7d target/arm: Convert Neon 3-reg-diff prewidening ops to decodetree 
Convert the "pre-widening" insns VADDL, VSUBL, VADDW and VSUBW
in the Neon 3-registers-different-lengths group to decodetree.
These insns work by widening one or both inputs to double their
size, performing an add or subtract at the doubled size and
then storing the double-size result.

As usual, rather than copying the loop of the original decoder
(which needs awkward code to avoid problems when source and
destination registers overlap) we just unroll the two passes.

Backports commit b28be09570d0827969b62b8f82b0f720a9915427 from qemu
