[Orlando Cazalet-Hyams via Phabricator via llvm-commits]

Orlando added a comment.

Just a note: This patch moves the `InstructionOrdering` class added in D86150 <https://reviews.llvm.org/D86150> out from DbgEntityHistoryCalculator.cpp to DbgEntityHistoryCalculator.h so that we're able to use it in `DebugHandlerBase`.
