Locations are no longer required by lalr1.cc.

* data/lalr1.cc (_b4_args, b4_args): New.
	Adjust all uses of locations to make them optional.
	* tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
	(AT_CHECK_NAMESPACE): Check the use of locations.
	* tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
	without locations with lalr1.cc.
	Test these cases.
	* tests/output.at: Check lalr1.cc with and without location
	support.
	* tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
	Don't use locations.
