test location_type.

* tests/local.at (_AT_BISON_OPTION_PUSHDEFS):
	Define AT_LOCATION_TYPE_IF.
	(_AT_BISON_OPTION_POPDEFS): Undefine AT_LOCATION_TYPE_IF.
	* tests/calc.at (_AT_DATA_CALC_Y): When %define location_type is
	used, provide a user location type and use it.
	(Simple LALR1 C++ Calculator): Add a test case for location_type.
