Heads-up, it currently fails on the following example:

  #define __rcu __attribute__((btf_type_tag("rcu")))
  
  struct cred;
  const struct cred *cred;
  void commit_creds()
  {
    cred = (typeof(*cred) __rcu *)(0);
  }

I'm working on the fix.
Also I missed the fact that D145891 <https://reviews.llvm.org/D145891> (actual 
BTF generation) needs adjustment as well.
