[PATCH] D28168: [LV] Update dominator tree before fixing external IV users

[Matthew Simpson via Phabricator via llvm-commits]

mssimpso updated this revision to Diff 83616.
mssimpso added a comment.

Added a FIXME comment indicating that we should work towards updating the dominator tree earlier.

Should we commit this now so we can close the PR before the 4.0 branch? We can later try to resolve the SCEV issues and keep the dominator tree up-to-date as we go.
