This feature is currently not supported in the compiler.
To facilitate this we emit a stub version of each kernel
function body with different name mangling scheme, and
replaces the respective kernel call-sites appropriately.
Fixes https://github.com/llvm/llvm-project/issues/60313
D120566 was an earlier attempt made to upstream a solution
for this issue.
