Remove comparison for polymorphic types.
2019-10-30 Martin Liska <mliska@suse.cz>
* ipa-icf-gimple.c (func_checker::func_checker): Do not
initialize m_compare_polymorphic.
(func_checker::compare_decl): Do not compare polymorphic types.
* ipa-icf-gimple.h (m_compare_polymorphic): Remove.
* ipa-icf.c (sem_function::equals_private): Do not call
compare_polymorphic_p.
