<pre>
    A DXIL category represents a set of DXIL operations with the same function signature. Implement a TableGen representation of DXIL category in `DXIL.td` to encapsulate valid parameter types of DXIL ops.

Implement the functionality in TableGen backend, DXILEmitter, to generate necessary C++ data structures and/or tables for lowering passes to consume the attribute information.
