Michael Zolotukhin 8f5cdd38cc [LoopUnroll] By default disable unrolling when optimizing for size. ... Summary: In clang commit r268509 we started to invoke loop-unroll pass from the driver even under -Os. However, we happen to not initialize optsize thresholds properly, which si fixed with this change. r268509 led to some big compile time regressions, because we started to unroll some loops that we didn't unroll before. With this change I hope to recover most of the regressions. We still are slightly slower than before, because we do some checks here and there in loop-unrolling before we bail out, but at least the slowdown is not that huge now.
