Thank you to everyone who has reviewed this pull request, other patches, and contributed to the SPIR-V backend in the last two years! This is a big milestone!

Please note that the failures in the SPIR-V Tests GitHub action are due to a known bug in spirv-val. This issue is being tracked in https://github.com/KhronosGroup/SPIRV-Tools/pull/5407. To prevent similar issues in the future, I will make changes to the GitHub action so that it references a specific revision of SPIR-V Tools. Updates to this reference will be done manually when the spec changes, so that such disruptions don't affect other contributors to the SPIR-V backend.

If there are no new comments or concerns, I plan to merge this pull request by the end of this week. Please feel free to share any additional feedback.
