Add address space identifiers to expression language for types.
	* c-exp.y (space_identifier, cv_with_space_id,
	const_or_volatile_or_space_identifier_noopt,
	const_or_volatile_or_space_identifier): New terminals.
	(ptype): Accept const_or_volatile_or_space_identifier.
	(typebase): Accept const_or_volatile_or_space_identifier.
	* c-typeprint.c (c_type_print_cv_qualifier): Rename to
	c_type_print_modifier.  Handle address space modified types.
	* gdbtypes.h (TYPE_FLAG_CODE_SPACE, TYPE_FLAG_DATA_SPACE):
	New type flags.
	(struct type): Add new field as_type for addr-space qualified types.
	(TYPE_AS_TYPE): New macro, retrieves the chain of types that are
	identical to this one except for address-space qualification.
	* gdbtypes.c (alloc_type): Initialize new field 'as_type'.
	(address_space_name_to_int): New function.
	(address_space_int_to_name): New function.
	(make_type_with_address_space): New function.
	(make_cv_type): Handle as_type field of new struct type object.
	* parse.c (check_type_stack_depth): New function.
	(push_type_address_space): New function.
	(follow_types): Handle types with address-space qualifier.
	* parser-defs.h (enum type_pieces): Add enum tp_space_identifier.
