It seems GlobalDecl is just a wrapper for concrete Decl's

https://github.com/llvm/llvm-project/blob/31817731167135870259ef1e7387746345b96a2f/clang/include/clang/AST/GlobalDecl.h#L40

Here we need to get the mangled name of a kernel and the mangled name of the same kernel but with a prefix before mangling.

Can I use GlobalDecl with the same FunctionDecl* but different multi-version index to indicate it is a kernel or a stub, then let the mangler mangle them differently?
