> We are instantiating multiple versions of templates in this module for cases that, byte-wise, do the exact same comparison. For example:
> * For equals, not_equals, we can use the same 32-bit/64-bit comparison kernels for signed int / unsigned int / floating point types of the same byte width
> * TimestampType can reuse int64 kernels, similarly for other date/time types
> * BinaryType/StringType can share kernels
> etc.
