[PATCH] D35570: [ORE] Port TailRecursionElimination to the new API

[Davide Italiano via Phabricator via llvm-commits]

davide created this revision.

I still need to add tests, but I wanted to make sure first we agree this is the right way of using the new API.
Unfortunately, no tests fail if I remove the calls to the old API.
