[tint][ir][ToProgram] Handle shadowing.

Change the ir::Module naming methods to allow for duplicate names.

Change the ir::Disassembler to ensure that IDs are uniquely named.
If the disassembler has an ID that does not match the value's
name, then a new comment is appended to the end of the instruction
with the value's ID and name.

Add a new RenameConflictsWGSL transform that renames declarations
which prevent identifiers from resolving to the correct
declaration, and those with identical identifiers declared in the
same scope.

This fixes all the known issues with shadowing which the
roundtrip fuzzer uncovered.

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.
