This reapplies:8ff85ed905Original commit message: As a follow-up to my initial mail to llvm-dev here's a first pass at the O1 described there. This change doesn't include any change to move from selection dag to fast isel and that will come with other numbers that should help inform that decision. There also haven't been any real debuggability studies with this pipeline yet, this is just the initial start done so that people could see it and we could start tweaking after. Test updates: Outside of the newpm tests most of the updates are coming from either optimization passes not run anymore (and without a compelling argument at the moment) that were largely used for canonicalization in clang.
