	PR 2056
	* translate.cxx (c_unparser::aggregation_locks): Keeps track of
	foreach's locks on pmaps to avoid extra aggregation.
	(c_unparser::visit_foreach_loop): Set aggregation_locks appropriately.
	(c_unparser::load_aggregate, mapvar::call_prefix, mapvar::get):
	Use a new parameter to indicate that we should read from the
	already-aggregated map rather than the full pmap..
	(c_unparser::visit_arrayindex c_unparser::visit_print_format,
	c_unparser::visit_stat_op): Use aggregation_locks to avoid taking a
	lock and aggregating the pmap.
	(c_unparser::emit_map_type_instantiations): To read from a pmap's
	aggregated map, we need to include map-gen.c for the _stp_map_*
	functions.
	(c_unparser::obtained_locks, varlock::varlock, varlock::~varlock):
	Add simple static checking to detect incompatible nested locks during
	translation, and flag it as an error.
