Look to L449 in valgrindTestSuite.sh:

```
    grep VALGRIND $file > /dev/null 2>&1
    if [ "$?" -ne "0" ]
    then
printNotImplementedString $htest
      continue
fi
```

Thus, if the token "VALGRIND" doesn't appear at all in the .test file (because it has been moved to harnessFunctions.sh), then the heuristics fails and the test will be marked as NOT IMPLEMENTED by valgrindTestSuite.sh

Of course, it has easy solutions (e.g. include `#VALGRIND` in some place in the .test file) but we have to take into account in this PR.
