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.

Return how Object may be captured before instruction I, considering only provenance captures.
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.
