The default value for MaxUsesToExplore argument.

It's relatively small to keep the cost of analysis reasonable for clients like BasicAliasAnalysis, where the results can't be cached. TODO: we should probably introduce a caching CaptureTracking analysis and use it where possible. The caching version can use much higher limit or don't have this cap at all.
