Will it be possible to use spirv-unknown-unknown in LLVM 15?

[nevi-me]

The spirv target started landing earlier this year [0], though it seems most of the active development is still happening on the KhronosGroup org/repos [1].

When Rust moves to LLVM 15 [2], will there be any benefit to this project? Will it be possible to use spirv-unknown-unknown, or is the rustc_codegen_spirv using a different approach?

I have no experience yet on compiler intrinsics, and I am curious as someone willing to learn and contribute.
