I don’t think fixing the SPIR-V function ordering in the LLVM IR linker is the right place and it’s SPIR-V emitters’ responsibility (e.g. SPIR-V backend and LLVM-SPIRV-Translator) to emit valid SPIR-V code - IOW, the fix should probably done in the emitters.

Also, there is a danger that the reordering done in the linker may be undone by follow up transformation passes.
