[tint] Emit `unreachable` as `return` for non-void functions The `PreventInfiniteLoops` transforms changes the control flow such that some `unreachable` instructions become statically reachable. This may upset some downstream compilers that want to ensure that non-void functions always return. There are various places that unreachable instructions show up, so just always emit them as `return` statements in the textual backends instead of only handling this in the infinite loop transform.

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:
