plugins: Ensure that loadInterface plugins can see annotations
loadInterface replaces the mi_decls
, mi_insts
, mi_fam_insts
,
mi_rules
, mi_anns
fields of ModIface with undefined
before
inserting the interface into the EPS. However, we still want to give
loadInterface plugins access to these fields. Consequently, we want to
pass the unmodified ModIface
the plugin.
