void LostDebugLocObserver::checkpoint ( bool CheckDebugLocs = true )

Call this to indicate that it's a good point to assess whether locations have been lost.

Typically this will be when a logical change has been completed such as the caller has finished replacing some instructions with alternatives. When CheckDebugLocs is true, the locations will be checked to see if any have been lost since the last checkpoint. When CheckDebugLocs is false, it will just reset ready for the next checkpoint without checking anything. This can be helpful to limit the detection to easy-to-fix portions of an algorithm before allowing more difficult ones.
