ResourceAllocatorManager::DeallocateMemory was correctly invalidating the
passed in allocation object. However, since the subclass
ResourceHeapAllocation class was not overriding the Invalidate method and
clearing out the D3D12Resource pointer, the resource ended up being tied
to the lifetime of the Texture object instead of being released on Destroy.
In Chromium, this bug was particularly egregious as it meant swap chain
texture cleanup was at the whims of the Javascript garbage collector.

2019-08-26 mark.satterthwaite OpImageTexelPointer needs to use an int coordinate type for GLSL, but not for MSL.
2019-08-26 mark.satterthwaite Remove obsolete memory barrier scope specification from Metal output, this API has been removed.
2019-08-14 mark.satterthwaite Add an option to SPIRV-Cross to enforce invariant floating point math to prevent different depth calculation between prepass & basepass when running on Metal 2.0 and earlier.
2019-08-14 mark.satterthwaite More fixes to handling packing & access elements in an array. Made in two parts. 1. Don't allow AccessChain operations to add duplicated swizzles when accessing packed arrays. 2. Only pack arrays when there is the proper amount of space between members in a struct, otherwise it will definitely be wrong.
2019-08-14 mark.satterthwaite Update the Metal shaders to account for changes in the shader compilation.
2019-08-14 mark.satterthwaite Fix texture swizzling.
2019-08-14 mark.satterthwaite The result of an AccessChain intrinsic in SPIRV can be referenced by multiple blocks but when they are loops that can result in compilation problems because the source variables might not be declared early enough. This forces us to hoist those variables high enough to make it work.
2019-08-14 mark.satterthwaite There are occasions where phi-variable copies are introduced for original variables which are fully declared, which coud result in the phi-variable never being declared and the shader not compiling, so declare the phi-variables when this happens. Change made in two parts. 1. Ensure that we declare phi-variable copies even if the original declaration isn't deferred. 2. Only flush phi variables once, avoids duplicate definitions.
2019-08-14 mark.satterthwaite When converting from HLSL the dxc SPIRV output often contains variables that are written through (e.g. a = b = c;) which seems to break the tracking of expressions in SPIRV-Cross, so don't reset everything once configured.
2019-08-14 mark.satterthwaite Provide the Metal bindings as part of the options structure as that is more convenient.
2019-08-14 mark.satterthwaite Slight modifications to IAB support for Metal output, so that the caller can specify an offset for the IAB start index, as for HLSL shaders UAVs need to occupy slots 0-7. The runtime support for SSBO robustness is also much simpler if the buffer size block is at index 0. Change made in two parts. 1. Allow the caller to specify the Metal translation should use argument buffers. 2. Move this to the front of IABs for convenience of the runtime.
2019-08-14 mark.satterthwaite Metal doesn't automatically enforce robust access to buffers unlike other APIs, so for storage-buffers, which become raw T* buffers in Metal, we need to fetch the buffer size and clamp the access to a valid index within the buffer ourselves. This is essential for shaders converted from HLSL which expects all resource access to be robust, though this implementation is technically different to the HLSL specification of return-0 for OOB reads, ignore OOB writes.
2019-08-14 mark.satterthwaite HLSL makes position calculations invariant by default to eliminate problems with depth-precision, Apple added a similar qualifier for Metal 2.1 that can and should be used in Vertex & Domain/TessEval shaders for the same effect.
2019-08-14 mark.satterthwaite When compiling from HLSL which pads and aligns float[]/float2[] within structures to float4[] we need to unpack the original type in Metal from the float4.
2019-08-14 mark.satterthwaite Fix conversion of the SampleMask intrinsic from SPIRV, where it is an array to Metal where it isn't.
2019-08-14 mark.satterthwaite Fixes to the generation of Metal tessellation shaders from SPIRV so that it works correctly in more complicated cases. First, when generating from HLSL before invoking the code that comes from the HLSL patch-function a control-flow and full memory-barrier are required to ensure that all the temporary values in thread-local storage for the patch are available. Second, the inputs to control and evaluation shaders must be properly forwarded from the global variables in SPIRV to the member variables in the relevant input structure. Finally when arrays of interpolators are used for input or output we need to add an extra level of array indirection because Metal works at a different granularity than SPIRV.
2019-08-14 mark.satterthwaite Work-around HLSL using zero-based InstanceID and VertexID variables, but SPIRV, like Metal, includes BaseInstance & BaseVertex. Until this can be fixed in DXC, which is really the proper place to solve this, we can decrement InstanceID & VertexID when the source is HLSL. Made in two parts. 1. Handle HLSL-style 0-based vertex/instance index. 2. We zero-base the InstanceID & VertexID variables for HLSL emulation elsewhere, so don't do it twice.
2019-08-14 mark.satterthwaite On iOS sub-passes can be implemented using the frame-buffer fetch API which is much more efficient than binding the textures. Change was made in three parts. 1. Use Metal's native frame-buffer fetch API for subpass inputs. 2. Make sure that frame-buffer-fetch is only available on iOS. 3. Default to using Metal's native frame-buffer fetch for subpass inputs on iOS.
2019-08-14 mark.satterthwaite SPIRV doesn't distinguish depth textures from regular textures, but Metal does, so if we've ever seen a depth comparison operation we must ensure that the texture is specified as a depth-texture.
2019-08-14 mark.satterthwaite Emulate texture atomics in Metal by binding the underlying buffer that backs the resource to a separate binding point and using that for Metal's atomic operations. This will work with texture_buffer and texture2d created from an MTLBuffer, so is perfect for emulating HLSL atomics on RWBuffer and sufficient, but not ideal, for RWTexture2D with some restrictions (limited format support and can't be used for render-targets).
2019-08-14 mark.satterthwaite Support Metal 2.1's texture_buffer type which is the equivalent to HLSL's Buffer/RWBuffer, so doesn't require modifying buffer sizes to match alignments.
2019-08-13 mark.satterthwaite In order to use Metal shader libraries properly you have to ensure that you have no duplicated global symbol names for different entities, otherwise 'metallib' won't be able to combine multiple shaders into a single library. This is broken into two parts. 1. Constant arrays of non-primitive types (i.e. matrices) won't link properly into Metal libraries. 2. Metal helper functions must be static force-inline otherwise they will cause problems when linked together in a single Metallib.
2019-08-13 mark.satterthwaite Rework the way arrays are handled in Metal to remove the array copies as they are unnecessary from Metal 1.2. There were cases where copies were not being inserted and others appeared unncessary, using the template type should allow the 'metal' compiler to do the best possible optimisation. The changes are broken into three stages. 1. Allow Metal to use the array<T> template to make arrays a value type. 2. Force the use of C style array declaration for some cases which cannot be wrapped with a template. 3. Threadgroup arrays can't have a wrapper type. 4. Tweak the code to use unsafe_array in a few more places so that we can handle passing arrays of resources into the shader and then through shaders into sub-functions. 5. Handle packed matrix types inside arrays within structs. 6. Make sure that builtin arguments still retain their array qualifiers when used in leaf functions. 7. Fix declaration of array-of-array constants for Metal so we can use the array<T> template.
2019-08-13 mark.satterthwaite UE4 shader reference for those shaders that will compile without the changes.
2019-08-13 mark.satterthwaite Port the UE4 spirv shaders to ASM shaders that can be used in the test-rig - this will help show why the changes are required.
2019-08-13 mark.satterthwaite Many interesting test cases for SPIRV-Cross taken from compiling UE4 shaders. These highlight the reasons for the various changes we've made.

Previously, the trace event buffer was cleared after *all* tests
completed. In order to avoid allocating a ton of space to hold
traces, this patch factors the trace event recording so that the
buffer is processed and reset at the end of each test trial.
This patch also prepares for the future where trace events will be
processed at the end of each trial to compute additional metrics.

webgpu.h is the "official" header for WebGPU in native and is being

dawn.h and dawncpp.h are changed to become webgpu.h and webgpu_cpp.h
respectively and use the new naming convention. New dawn.h and dawncpp.h
headers are created that just proxy the types, constants and functions
to their WebGPU counterpart.
Almost no naming change is done in Dawn in this commit, which help check
that the proxying headers work correctly. A couple changes were
necessary, in particular for tests of the internal of dawncpp.h, and a
workaround for a standard library bug for std::underlying_type was
removed because it is no longer needed and got in the way.
