IPA ICF: enhance hash value calculated in TU
* ipa-icf-gimple.h (return_with_result): Add missing colon to dump.
* ipa-icf.c (sem_function::get_hash): Hash new declaration properties.
(sem_item::add_type): New function.
(sem_function::hash_stmt): Add TREE_TYPE of gimple_op.
(sem_function::compare_polymorphic_p): Do not consider indirect calls.
(sem_item_optimizer::update_hash_by_addr_refs): Add ODR type to hash.
(sem_function::equals_wpa): Fix typo.
* ipa-icf.h (sem_item::add_type): New function.
(symbol_compare_hashmap_traits): Replace hashing of pointer with symbol
order.
