types. Examples of quantized types are TF_Qint8 or TF_Quint8.

An example is TF_DequantizeOp, which converts a quantized type to a float.
This op is rewritten to generic ops that perform the scale and shift
and can operate on non-quantized types.

Currently, TF_DequantizeOp is the only op with a lowering that falls
in this category. When more lowerings are added (e.g. QuantizeV2Op),
