Friend class name lookup 5/n
PR c++/1016
* cp-tree.h (pushtag): Adjust declaration.
* decl.c (lookup_and_check_tag): Call lookup_type_scope if
lookup_name fails.
(xref_tag): Adjust call to pushtag. Make hidden class visible.
(start_enum): Adjust call to pushtag.
* name-lookup.c (ambiguous_decl): Ignore hidden names.
(qualify_lookup): Change return type to bool.
(hidden_name_p): New function.
(lookup_namespace_name, unqualified_namespace_lookup,
lookup_name_real): Use it.
(lookup_type_scope): Update comments.
(maybe_process_template_type_declaration): Change parameter name
from globalize to is_friend.
(pushtag): Change globalize parameter of type int to tag_scope.
Hide name if introduced by friend declaration.
* name-lookup.h (hidden_name_p): Add declaration.
* parser.c (cp_parser_lookup_name): Don't deal with hidden name
here.
* pt.c (push_template_decl_real): Make hidden class template
visible.
(lookup_template_class, instantiate_class_template): Adjust call
to pushtag.
* semantics.c (begin_class_definition): Likewise.
* rtti.c (init_rtti_processing, build_dynamic_cast_1,
tinfo_base_init, emit_support_tinfos): Use ts_current instead of
ts_global.
