Quirk terminology was deemed to be inappropriate for describing the features/extensions of a device. It has been replaced with traits which is far more fitting but quirks will be used as a terminology for errata in devices.
Shader programs allocate instructions and blocks within an `ObjectPool`, there was a global pool prior that was never reaped aside from on destruction. This led to a leak where the pool would contain resources from shader programs that had been deleted, to avert this the pools are now tied to shader programs.
An assumption was hardcoded into `Shader::Profile` regarding devices supporting demotion of shader invocations to helpers. This assumption wasn't backed by enabling the `VK_EXT_shader_demote_to_helper_invocation` extension via a quirk leading to assertions when it was used by the shader compiler, a quirk has now been added for the extension and is supplied to the shader compiler accordingly.
Add support for parsing and combining `VertexA` and `VertexB` programs into a single vertex pipeline program prior to compilation, atomic reparsing and combining is supported to only reparse the stage that was modified and recombine once at most within a single pipeline compilation.
Shader compilation is now broken into shader program parsing and pipeline shader compilation which will allow for supporting dual vertex shaders and more atomic invalidation depending on runtime state limiting the amount of work that is redone.
Bindings are now properly handled allowing for bound UBOs to be converted to the appropriate host UBO as designated by the shader compiler by creating Vulkan Descriptor Sets that match it.
An instance of `Shader::Backend::Bindings` must be retained across all stages for correct emission of bindings, which is now done inside `GraphicsContext::GetShaderStages`.
Graphics shaders can now be compiled using the shader compiler and emit SPIR-V that can be used on the host. The binding state isn't currently handled alongside constant buffers and textures support in `GraphicsEnvironment` yet.
Introduces the `supportsShaderViewportIndexLayer` quirk and sets `Shader::Profile::support_int64_atomics` depending on if the `supportsAtomicInt64` quirk is available.
Introduces the `floatControls`, `supportsSubgroupVote` and `subgroupSize` quirks for the shader compiler which are based on Vulkan `PhysicalDevice` properties.
Introduces several quirks for optional features used by the shader compiler which are now reported in the `Shader::HostTranslateInfo` and `Shader::Profile` structure. There are still property-related quirks for the shader compiler which haven't been implemented in this commit.
This class will be entirely responsible for any interop with the shader compiler, it is also responsible for caching and compilation of shaders in itself.
