Subject: alias.c (struct alias_set_entry): New field has_zero_child.

	* alias.c (struct alias_set_entry): New field has_zero_child.
	(mem_in_disjoint_alias_sets_p): Return 0 if set in either ase.
	(get_alias_set): If language-dependent routine set TYPE_ALIAS_SET,
	do nothing.
	Call record_component_aliases for aggregate types.
	(record_alias_subset): Set has_zero_child.
	(record_component_aliases, case ARRAY_TYPE): Do nothing if
	TYPE_NONALIASES_COMPONENT.
	(record_component_aliases, case RECORD_TYPE): Test
	DECL_NONADDRESSABLE_P.
	* c-decl.c (grokdeclarator): Set DECL_NONADDRESSABLE_P instead
	of TREE_ADDRESSABLE.
	* calls.c (initialize_argument_information): Only test
	TYPE_TRANSPARENT_UNION for UNION_TYPE.
	* function.c (assign_parms): Likewise.
	* integrate.c (function_cannot_inline_p): Likewise.
	* stor-layout.c (finish_record_layout): Don't call
	record_component_aliases.
	* tree.h (struct tree_int_cst): Use struct tree_common.
	(struct tree_real_cst, struct tree_string): Likewise.
	(struct tree_complex, struct tree_identifier): Likewise.
	(struct tree_list, struct tree_vec, struct tree_exp): Likewise.
	(struct tree_block, struct tree_type, struct tree_decl): Likewise.
	(TYPE_TRANSPARENT_UNION): Use UNION_TYPE_CHECK.
	(TYPE_NONALIASES_COMPONENT): New macro.
	(TYPE_AMBIENT_BOUNDEDNESS): Use FUNCTION_TYPE_CHECK.
	(DECL_NONADDRESSABLE_P): New macro.
	(struct tree_decl): Reorder bits for clarity of how many left;
	add non_adressable.
	* cp/cp-tree.h: Use struct tree_common instead of a char array.
	* cp/decl.c (grokdeclarator): Set DECL_NONADDRESSABLE_P instead
	of TREE_ADDRESSABLE.
