With IMA we have compatible structs which do not set the 
TYPE_MAIN_VARIANT
to one other because of they are not variants to one another until after
the front-end is finished with them.

What could be done is a pass which takes the compatible structs and 
make them
one type thus being able to remove the language hook.
