Hal Finkel b4b78bf273 Move the CapturesBefore tracker from AA into CaptureTracking ... There were two generally-useful CaptureTracker classes defined in LLVM: the simple tracker defined in CaptureTracking (and made available via the PointerMayBeCaptured utility function), and the CapturesBefore tracker available only inside of AA. This change moves the CapturesBefore tracker into CaptureTracking, generalizes it slightly (by adding a ReturnCaptures parameter), and makes it generally available via a PointerMayBeCapturedBefore utility function. This logic will be needed, for example, to perform noalias function parameter attribute inference. No functionality change intended. llvm-svn: 213519		2014-07-21 13:15:48 +00:00
