VectorAPI Testing Infrastructure custom loop trip count

Initial tests I created locally for Vector API were done using a mix of both techniques - namely both an outer loop repeating the computation body loop and multiple invocation counts. This was done to ensure tests run for an adequate amount of time to allow compilation to happen while also allowing exercising of both on-stack replacements and whole method computation of code with Vector API. Thus I still have some preference for multiple invocation counts but I think we could probably do without. That said, I worry that the current trip count of 10 is too small and won't have the same chances of successful compilation as 10 invocations - I do like that it can be changed dynamically but I wonder if we can select a higher default, like 100.
