Right now we only support the SPIR-V instructions OpLine/OpNoLine, Rust-GPU does its own custom instructions to add a bit more information, and there's also SPIR-T-only attributes:
Ideally, though, we could interop with SPIR-V's equivalents of DWARF:
Sadly, they each have drawbacks/limitations, so we probably need to do a tiered system where we can express all of their metadata (e.g. as weirdly-typed Consts) and only convert some of them into SPIR-T-native attributes etc. - at the very least, we should be able to do correct passthru even of features that Rust-GPU itself doesn't use/need.
