tint: Implement sem::Load The resolver now wraps sem::Expression objects with a sem::Load object anywhere that the load rule is invoked. sem::Expression provides an `UnwrapLoad()` method that returns the inner expression (or passthrough, if no load is present), which is analaguous to Type::UnwrapRef(). The logic for alias analysis in `RegisterLoadIfNeeded` has been folded into the new `Resolver::Load` method. Fixed up many transforms and tests. The only difference in output is for a single SPIR-V backend test, where some IDs have changed due to slight re-ordering of when expressions are generated. There may be further clean-ups possible (e.g. removing unnecessary calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or transforms that deal with memory accesses), but these can be addressed in future patches.

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:
