Unlike the "LD1D (scalar + vector)" etc instructions, LD1Q is vector + scalar. This means that: * the vector and the scalar register are in opposite fields in the encoding * 31 in the scalar register field is XZR, not XSPThe same applies for ST1Q. This means we can't reuse the trans_LD1_zprz() and trans_ST1_zprz() functions for LD1Q and ST1Q. Split them out to use their own trans functions. Note that the change made here to sve.decode requires the decodetree bugfix "decodetree: Infer argument set before inferring format" to avoid a spurious compile-time error about "dtype".
