# MulAdd — integer MLA and fused floating-point FMLA: Zda += Zn * Zm. Both are
# predicated-only and accumulating: the destination <Zda> is read as well as
# written but is not named among the assembly inputs, so the loader
# synthesizes the accumulator input (see the emitOne comment in sve/emit.go).
# operandOrder 231Type1 gives the NEON operand convention x.MulAdd(y, z) with
# the accumulator z last, while the machine op keeps it pinned first.
