value of the input by 255/6 and cast to quint8.

If the output type was qint8 ([-128, 127]), the operation will additionally
subtract each value by 128 prior to casting, so that the range of values aligns
with the range of qint8.

If the mode is 'MIN_FIRST', then this approach is used:

```
num_discrete_values = 1 << (# of bits in T)

			x := v_0

				continue
			}
			_ = v_1.Args[1]
			v_1_0 := v_1.Args[0]

		if !(int8(x) < y && uint8(x) > uint8(y)) {

		v.reset(OpAMD64FlagLT_UGT)

	// match: (CMPBconst (MOVLconst [x]) [y])
	// cond: int8(x)>y && uint8(x)<uint8(y)
