Detailed Description
Context-sensitive CaptureAnalysis provider, which computes and caches the earliest common dominator closure of all captures.
It provides a good approximation to a precise "captures before" analysis.

Check whether Object is not captured before instruction I.
If OrAt is true, captures by instruction I itself are also considered.
If I is nullptr, then captures at any point will be considered.
Implements llvm::CaptureAnalysis.
