	for better storage.
	(polymorphic_call_target_hasher::hash): Hash SPECULATIVE.
	(possible_polymorphic_call_targets): Instead of computing both
	speculative and non-speculative answers, do just one at a time.
	Replace NONSPECULATIVE_TARGETSP parameter with SPECULATIVE flag.
	(dump_targets): Break out from ...
	(dump_possible_polymorphic_call_targets): ... here; dump both speculative
	and non-speculative lists.
	(ipa_devirt): Update for new possible_polymorphic_call_targets API.
