Range Analysis: Get loop control variable from loop initializer

This patch is the first part to implement the computation of the
range on the loop control variables. In this patch we implement the
helper function `GetLoopControlVariableFromConstantInitializer()` to
get the pointer of the loop control variable from the loop initializer
block when the block satisfy below conditions:
- There are only two statements in the loop initializer block.
- The first statement is to initialize the loop control variable
  with a constant value.
- the second statement is `next_iteration`.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.
