Good idea. Added in r350351 (https://reviews.llvm.org/rL350351)

Log:
[CaptureTracking] Pass MaxUsesToExplore from wrappers to the actual implementation
    This is a follow up for rL347910. In the original patch I somehow forgot to pass
the limit from wrappers to the function which actually does the job.
