[PATCH] D52716: [Inliner] Penalise inlining of calls with loops at Oz

[Dave Green via Phabricator via llvm-commits]

Now ignores loops that will never be executed. I also have some code that uses SCEV to calculate if the backedge count is <= 1 and allow inlining there. It doesn't seem to come up very often though and needed some plumbing to get SE's/TLI's in the right places.

Eli, what do you think between this and https://reviews.llvm.org/D53405?
