* ipa-icf.c (sem_function::equals_wpa): Match CXX_CONSTRUCTOR_P
and CXX_DESTURCTOR_P. For consutrctors match ODR type of class they
are building; for methods check ODR type of class they belong to if
they may lead to a polymorphic call.
(sem_function::compare_polymorphic_p): Be bit smarter about testing
when function may lead to a polymorphic call.
(sem_function::compare_type_list): Remove.
(sem_variable::equals): Update use of compatible_types_p.
(sem_variable::parse_tree_refs): Remove.
(sem_item_optimizer::filter_removed_items): Do not filter out CXX
cdtor.
* ipa-icf-gimple.c (func_checker::compare_decl): Do polymorphic
matching here.
(func_checker::compatible_polymorphic_types_p): Break out from ...
(unc_checker::compatible_types_p): ... here.
* ipa-icf-gimple.h (func_checker::compatible_polymorphic_types_p):
Declare.
(unc_checker::compatible_types_p): Update.
* ipa-icf.h (compare_type_list, parse_tree_refs, compare_sections):
Remove.
