// For 386/AMD64 register list specifies 4VNNIW-style multi-source operand.
// For range of 4 elements, Intel manual uses "+3" notation, for example:
//
//	VP4DPWSSDS zmm1{k1}{z}, zmm2+3, m128
//
// Given asm line:
//
//	VP4DPWSSDS Z5, [Z10-Z13], (AX)
//
// zmm2 is Z10, and Z13 is the only valid value for it (Z10+3).
// Only simple ranges are accepted, like [Z0-Z3].
