[PATCH v14 0/4] 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.

--
  v14: vkd3d-shader/spirv: Declare the phase SPIR-V function in spirv_compiler_enter_shader_phase().
       vkd3d-shader/spirv: Remove the hull shader phase array.
       vkd3d-shader/trace: Trace the normalised instruction array after tracing the input.
       vkd3d-shader/ir: Merge all shader IR fork and join phases into a single phase.
