Could you please rebase on main and update the spirv-headers hash in DEPS to point to at least the merged headers for this extension?

Hi @alan-baker , done and done.

[alan-baker]

Overall there seem to be a lack of tests for this functionality. Please add some tests for the new validation.

Separately, when reading the spec for this extension you seem to be validating things that are missing from the spec. I'd suggest double checking and updating the extension text to match this validation.

The optimizer changes look good to me.

@yavn could you please rebase this change and fix the formatting and any build errors?

[yavn]

I'll see if there are any new failures once the checks are done. I used merges during the review, so please squash it on submit if a linear history is preferred. Thanks.

[alan-baker]

The asan failure looks real. The smoketest should be resolved with another rebase.

Thanks for taking a look. Okay, it's probably due to that nested new at test/opt/type_manager_test.cpp:182:32. I will fix it tomorrow.
