        ipa_reference_local_vars_info_t, ipa_reference_global_vars_info_t,
        ipa_reference_vars_info_t): Move here from ipa-reference.h
        (node_duplication_hook_holder, node_removal_hook_holder): New.
        (get_reference_vars_info_from_cgraph): Rename to ...

Remove.
        (ipa_reference_get_read_global, ipa_reference_get_not_read_global
