Fix some errors that were causing testsuite failures for GLR.

Browse Source 
* data/glr.c (yy_reduce_print): Change yyrhsVals to yyvsp to remove
	compiler errors when using %debug.
	Add declaration of yylow when locations in use to avoid compilation
	error.
	(yyglrReduce): Conditionalize message "Parse ... rejected by rule..."
	on whether we are in split mode, for consistency with behavior of
	non-GLR parsing.
