Is it intended that creating a named node leaves a hole in the table we're processing, and instead puts the named node in another table which collects all the named nodes? It doesn't leave a hole because the `continue` statement skips the count incrementation. I added comments to clarify what's happening here.

This means that the DXBC signature is replaced with the DXIL signature as far as the parser is concerned. That means that the VSIR code (and, say, the SPIR-V code downstream) is generated from a potentially different signature than what is returned by `vkd3d_shader_scan()`. I guess that could be confusing for the client. The same applies to TPF due to signature normalisation. The DXBC signature expresses the same info in different form. `struct vkd3d_shader_signature_element` doesn't support register counts, so if a reason arises for clients to access SM 6 signature info, we would need to extend the ABI.
