vkd3d-shader/hlsl: Introduce hlsl_ir_vsir_instruction_ref.

Browse Source 
This node type will be deleted once the hlsl->vsir->d3dbc translation is
complete. For now it serves the purpose of allowing to keep both real
hlsl_ir_nodes and vsir_instructions in the hlsl_block, until all the
former can be translated into the latter.
