[tint][ir] Further simplify FromProgram

Use a stack of tasks to walk and evaluate expressions. Uses fewer stacks and only type dispatches once per expression node.

Move all the expressions emission functions into EmitExpression() to prevent them accidentally being called by other emission functions. This reduces the expression related methods to just EmitExpression() and EmitValueExpression().

Move expr_to_result_ into EmitExpression(), substantially reducing the lifetime of this map, and reducing the likelihood it would spill to the heap.

Emit loads at expression emission time instead of when fetching the result. This is more truthful to the semantic info.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
