I wanted to handle the most common case (no DECL_ATTRIBUTES at all) and the
second most common case (lookup_attribute returning NULL) inline, otherwise
we'll do an extra function call for all builtins in all cases.
But if you strongly prefer that lookup to be in duplicate_one_attribute,
I can change the patch and retest.
