gdb/ChangeLog:

	* ada-lang.c (user_select_syms): Only fetch symtab if symbol is
	objfile-owned.
	(cache_symbol): Ignore symbols that are not objfile-owned.
	* block.c (block_objfile): New function.
	(block_gdbarch): New function.
	* block.h (block_objfile): Declare.
	(block_gdbarch): Declare.
	* c-exp.y (classify_name): Remove call to
	language_lookup_primitive_type.  No longer necessary.
	* gdbtypes.c (lookup_typename): Call lookup_symbol_in_language.
	Remove call to language_lookup_primitive_type.  No longer necessary.
	* guile/scm-symbol.c (syscm_gdbarch_data_key): New static global.
	(syscm_gdbarch_data): New struct.
	(syscm_init_arch_symbols): New function.
	(syscm_get_symbol_map): Renamed from syscm_objfile_symbol_map.
	All callers updated.  Handle symbols owned by arches.
	(gdbscm_symbol_symtab): Handle symbols owned by arches.
	(gdbscm_initialize_symbols): Initialize syscm_gdbarch_data_key.
	* language.c (language_lookup_primitive_type_1): New function.
	(language_lookup_primitive_type): Call it.
	(language_alloc_type_symbol): New function.
	(language_init_primitive_type_symbols): New function.
	(language_lookup_primitive_type_as_symbol): New function.
	* language.h (struct language_arch_info) <primitive_type_symbols>:
	New member.
	(language_lookup_primitive_type): Add function comment.
	(language_lookup_primitive_type_as_symbol): Declare.
	* printcmd.c (address_info): Handle arch-owned symbols.
	* python/py-symbol.c (sympy_get_symtab): Ditto.
	(set_symbol): Ditto.
	(sympy_dealloc): Ditto.
	* symmisc.c (print_symbol): Ditto.
	* symtab.c (fixup_symbol_section): Ditto.
	(lookup_symbol_aux): Initialize block_found.
	(basic_lookup_symbol_nonlocal): Try looking up the symbol as a
	primitive type.
	(initialize_objfile_symbol_1): New function.
	(initialize_objfile_symbol): Call it.
	(allocate_symbol): Call it.
	(allocate_template_symbol): Call it.
	(symbol_objfile): Assert symbol is objfile-owned.
	(symbol_arch, symbol_symtab, symbol_set_symtab): Ditto.
	* symtab.h (struct symbol) <owner>: Replaces member "symtab".
	(struct symbol) <is_objfile_owned>: New member.
	(SYMBOL_OBJFILE_OWNED): New macro.
	* cp-namespace.c (cp_lookup_bare_symbol): New arg langdef.
	All callers updated.  Try to find the symbol as a primitive type.
	(lookup_namespace_scope): New arg langdef.  All callers updated.
	Call cp_lookup_bare_symbol directly for simple bare symbols.
