[PATCH] D42717: [JumpThreading] sync DT for LVI analysis (PR 36133)

[Brian Rzycki via Phabricator via llvm-commits]

brzycki updated this revision to Diff 134239.
brzycki added a comment.

Added asserts to `enableDT` / `disableDT` to verify both `DT` and `DisabledDT` are never both valid pointers. Added a final `LVI->enabledDT()` at the very end of `runImpl` to allow subsequent passes to use `DT` with the cached `LVI` object.
