	PR fortran/48636
	* ipa-inline.h (condition): New fields offset, agg_contents and by_ref.
	* ipa-inline-analysis.c (agg_position_info): New type.
	(add_condition): New parameter aggpos, also store agg_contents, by_ref
	and offset.
	(dump_condition): Also dump aggregate conditions.
	(evaluate_conditions_for_known_args): Also handle aggregate
	conditions.  New parameter known_aggs.
	(evaluate_properties_for_edge): Gather known aggregate contents.
	(inline_node_duplication_hook): Pass NULL known_aggs to
	evaluate_conditions_for_known_args.
	(unmodified_parm): Split into unmodified_parm and unmodified_parm_1.
	(unmodified_parm_or_parm_agg_item): New function.
	(set_cond_stmt_execution_predicate): Handle values passed in
	aggregates.
	(set_switch_stmt_execution_predicate): Likewise.
	(will_be_nonconstant_predicate): Likewise.
	(estimate_edge_devirt_benefit): Pass new parameter known_aggs to
	ipa_get_indirect_edge_target.
	(estimate_calls_size_and_time): New parameter known_aggs, pass it
	recrsively to itself and to estimate_edge_devirt_benefit.
	(estimate_node_size_and_time): New vector known_aggs, pass it o
	functions which need it.
	(remap_predicate): New parameter offset_map, use it to remap aggregate
	conditions.
	(remap_edge_summaries): New parameter offset_map, pass it recursively
	to itself and to remap_predicate.
	(inline_merge_summary): Also create and populate vector offset_map.
	(do_estimate_edge_time): New vector of known aggregate contents,
	passed to functions which need it.
	(inline_read_section): Stream new fields of condition.
	(inline_write_summary): Likewise.
	* ipa-cp.c (ipa_get_indirect_edge_target): Also examine the aggregate
