[Migrated] Some shaders that compiled in 0.8 are erring in 0.9

Issue automatically imported from old repo: https://github.com/EmbarkStudios/rust-gpu/issues/1089
Old labels: t: bug
Originally creatd by schell on 2023-08-03T20:42:54Z

Expected Behaviour

Shaders should compile.

Example & Steps To Reproduce

Shaders that previously compiled in 0.8 are no longer compiling when bumping rust-gpu, spirv-std and spirv-builder to 0.9.

Specifically the shaders in question all give some form of this error:

error: error:0:0 - In Logical addressing, variables may not allocate a pointer type
         %24 = OpVariable %_ptr_Private__ptr_Private_uint Private %25
  |
  = note: spirv-val failed
  = note: module `/Users/schell/code/renderling/shaders/shader-crate/target/spirv-unknown-vulkan1.2/release/deps/shader_crate.spvs/main_fragment_scene.spv`

1. git clone https://github.com/schell/renderling --branch chore/bump-rust-gpu-0.9
2. cd renderling/shaders
3. cargo run --release

Clone renderling at the chore/bump-rust-gpu-0.9 branch, enter renderling/shaders, and run cargo run --release to reproduce the SPIR-V validation error. Inspect the generated shader artifact and the Rust GPU, spirv-std, and spirv-builder version changes. Done means the affected shaders compile successfully and spirv-val accepts the generated SPIR-V.
