Log message:
	Allow indirect primary bases.
	* cp-tree.h (struct lang_type): Remove vfield_parent.  Add
	primary_base.
	(CLASSTYPE_VFIELD_PARENT): Remove.
	(CLASSTYPE_PRIMARY_BINFO): Reimplement.
	(BINFO_PRIMARY_BINFO): Remove.
	(CLASSTYPE_HAS_PRIMARY_BASE_P): Reimplement.
	(BINFO_VBASE_PRIMARY_P): Likewise.
	(BINFO_PRIMARY_BASE_OF): New macro.
	(BINFO_INDIRECT_PRIMARY_P): Likewise.
	(get_primary_binfo): New function.
	* decl.c (lang_mark_tree): Make lang_type::primary_base.
	* class.c (vcall_offset_data_s): Rename to ...
	(vtbl_init_data_s): ... this.  Rename primary_p to primary_vtbl_p,
	and add ctor_vtbl_p.
	(get_derived_offset): Use get_primary_binfo.
	(dfs_mark_primary_bases): Adjust handling of virtual primary
	bases.
	(mark_primary_bases): Likewise.
	(set_primary_base): Take a binfo, not an integer, as a
	representation of the primary base.
	(indirect_primary_base_p): Remove.
	(determine_primary_base): Adjust for indirect primary bases.
	(dfs_find_final_overrider): Fix typo in coment.
	(update_vtable_entry_for_fn): Use get_primary_binfo.
	(layout_nonempty_base_or_field): Tweak.
	(build_base_fields): Adjust for new primary base semantics.
	(dfs_propagate_binfo_offsets): Remove.
	(propagate_binfo_offsets): Rewrite.
	(dfs_set_offset_for_shared_vbases): Remove.
	(layout_virtual_bases): Don't use it.
	(layout_class_type): Set CLASSTYPE_SIZE correctly under the new
	ABI.
	(finish_struct_1): Set CLASSTYPE_PRIMARY_BINFO, not
	CLASSTYPE_VFIELD_PARENT.
	(dfs_get_primary_binfo): New function.
	(get_primary_binfo): Likewise.
	(dump_class_hierarchy_r): Tweak printing of primary bases.
	(build_vtbl_initializer): Fix typo in comments.  Use
	vtbl_init_data.
	(build_vcall_and_vbase_vtbl_entries): Likewise.
	(build_vbaes_offset_vtbl_entries): Likewise.

	BV_VCALL_INDEX to handle indirect primary bases.
	(build_vcall_offset_vtbl_entries): Use vtbl_init_data.
	(build_rtti_vtbl_entries): Likewise.
