Consider removing all logic where we elide or infer a "time-" prefix

```
If I have a method called "timeIt" we report that as "It", and I believe we
accept it in -b as "It" as well.

I think this will bite us in the ass when we move to an (optional or required)
annotation-based approach for identifying benchmark methods.

We can probably lose all of that. For now, "time" would be significant only in
that all benchmark methods start with that, but we don't have to try to get
cute with inferring it and whatnot.
