Description
When atomicCompareExchangeWeak is called in compute shader, on a GL backend, wgpu will report internal error:

Caused by:
      In Device::create_compute_pipeline
        Internal error: Unable to write type Struct { members: [StructMember { name: Some("old_value"), ty: [3], binding: None, offset: 0 }, StructMember { name: Some("exchanged"), ty: [8], binding: None, offset: 4 }], span: 8 }

Repro steps
I'm reusing a repo I created for exploring other things: https://github.com/suguruwataru/wgsl-loop
The branch atomic-compare-exchange-weak contains a test that just runs a compute shader calling
atomicCompareExchangeWeak:
https://github.com/suguruwataru/wgsl-loop/tree/atomic-compare-exchange-weak

cargo test to run it, and you should see the internal error being reported.

Expected vs observed behavior
Expectation is atomicCompareExchangeWeak won't cause an internal error and be successfully translated.

Platform
I was running it on Linux without Vulkan driver. I have tried wgpu 23.0.1 and wgpu 25.0.0.
