Convert the VFP fused multiply-add instructions (VFNMA, VFNMS, VFMA, VFMS) to decodetree. Note that in the old decode structure we were implementing these to honour the VFP vector stride/length. These instructions were introduced in VFPv4, and in the v7A architecture they are UNPREDICTABLE if the vector stride or length are non-zero. In v8A they must UNDEF if stride or length are non-zero, like all VFP instructions; we choose to UNDEF always.
