[PATCH] D13443: Rework the LTO Pipeline, aligning closer to the O2/O3 pipeline.

[Teresa Johnson via llvm-commits]

Unfortunately, we haven't had a lot of success running LTO on our
internal benchmarks in the past due to the scaling issue.

That's great it is giving you better performance - I was just
surprised that it was beneficial to skip all of those downstream
optimizations in the initial compile step. Is the better performance
coming from skipping the initial inline? Is there no benefit to doing
the peepholes etc in the initial compile?
