    Try to resolve paths in threader without looking further back.


I am seeing a strange problem starting with this revision.  The spec 2017 test
case 500.perlbench is producing a few extraneous lines of output which is
causing it to fail.

These extra lines come from here in the perl code:

    if ($opts->{'calctol'}) {
        push @errstats, 'Calculated tolerances:';
        foreach my $type (qw(abstol reltol obiwan skiptol)) {
            if (exists($max->{$type}) && ($max->{$type} >= 0)) {
                push @errstats, sprintf "Maximum $type: %-10.5e",
$max->{$type};
            }
            if (exists($min->{$type}) && ($min->{$type} >= 0)) {
                push @errstats, sprintf "Minimum $type: %-10.5e",
$min->{$type};
            }
            if (exists($errcnt->{$type}) && ($errcnt->{$type} >= 0)) {
                push @errstats, "# of $type errors: ".$errcnt->{$type};
            }
            if (exists($opts->{"skip$type"}) && ($opts->{"skip$type"} > 0)) {
                push @errstats, "# of skip$type unused: ".$opts->{"skip$type"};
            }
        }
    }

So it appears that either the results of the perl exists function changed or
the values that are being checked did not exist before but do now.
