Convert the VSEL instructions to decodetree. We leave trans_VSEL() in translate.c for now as this allows the patch to show just the changes from the old handle_vsel(). In the old code the check for "do D16-D31 exist" was hidden in the VFP_DREG macro, and assumed that VFPv3 always implied that D16-D31 exist. In the new code we do the correct ID register test. This gives identical behaviour for most of our CPUs, and fixes previously incorrect handling for Cortex-R5F, Cortex-M4 and Cortex-M33, which all implement VFPv3 or better with only 16 double-precision registers.
