[PATCH v10 0/8] MR84: vkd3d-shader/spirv: Merge all shader IR fork and join phases into a single phase.

[Conor McCarthy (＠cmccarthy)]

Normalise the incoming vkd3d_shader_instruction IR to the shader model 6 pattern where only one patch constant function is emitted. This allows generation of a single patch constant function in SPIR-V.

  v10: vkd3d-shader/normalise: Insert hull shader control point input declarations if no control point phase is defined.
       vkd3d-shader/spirv: Delete an unnecessary call to spirv_compiler_get_register_id().
