Arithmetics counter fails if only one parameter is given

[hkaiser]

The performance counters /arithmetic/<operation> fail if only one counter is passed as the parameter, However, at least the counters add, multiply, and subtract should function just fine if only one argument is given.

Pat reported that things got even worse than before.

now it doesn't work with -t(anything) for papi counters

So I cannot use papi counters at all with top of trunk
