[llvm] r342387 - [GVNHoist] Re-enable GVNHoist by default

Hi Eric,

Thanks for your feedback. I am not actively working on GVN-Hoist, but I’ll take a look at these benchmarks at some point. We can keep it reverted for the time being. My take is that the community should get more involved if GVN-Hoist is an optimization we would like to re-enable. I felt I was a bit on my own trying to get it to a good state.
