I'd suggest a different direction. I've mentioned a couple of times that
having a builtin for obtaining the mangled name for a function reference
would be useful. One common use case of that is dlopen, but this is
actually another. So instead of changing the ifunc attribute parser
accept expressions that can be folded to string constants and then the
mangled-name builtin.
