[PATCH] D56284: [UnrollRuntime] Fix domTree failure in multiexit unrolling

[Anna Thomas via Phabricator via llvm-commits]

anna updated this revision to Diff 180269.
anna added a comment.

The IDom can be any block within the loop (as mentioned in the comment).
So, we need to check for IDom *contained* in the loop.
Added test case shows where the IDom is within the inner loop of the original loop.
Both test cases pass now with the fix.
