enable informing arithmetic parser of implicit units
This is so that "runtime=100" can be interpreted as 100 seconds rather than 100 microseconds, but runtime=(100ms + 100s) can also get the right answer (in microseconds). Signed-off-by: Stephen M. Cameron <stephenmcameron@gmail.com> Signed-off-by: Jens Axboe <axboe@fb.com>
