Introduce MaxUsesToExplore argument to capture tracking
Currently CaptureTracker gives up if it encounters a value with more than 20
uses. The motivation for this cap is to keep it relatively cheap for
BasicAliasAnalysis use case, where the results can't be cached. Although, other
clients of CaptureTracker might be ok with higher cost. This patch introduces an
argument for PointerMayBeCaptured functions to specify the max number of uses to
explore. The motivation for this change is a downstream user of CaptureTracker,
but I believe upstream clients of CaptureTracker might also benefit from more
fine grained cap.
