[committed] Fix some errors that were causing testsuite failures for GLR.

[Paul Hilfinger]

        * 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.
