Fix forward-reference errors for folded SPIR-V instructions. When instructions are folded in the SPIR-V printer, they assume they do not have a value in the `value_` map, and one is added. However, if the id was pre-allocated, this add will fail. The users of these instructions results will then use an id that is undefined. This CL introduces a FoldTo helper in the printer. If the result ID has already been pre-allocated, FoldTo emits an OpCopyObject to define the pre-allocated ID. Otherwise, it simply maps the value to the folded ID.

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:
