This change also introduces a link-time optimization level of 1. This optimization level runs only the globaldce pass as well as cleanup passes for passes that run at -O0, specifically simplifycfg which cleans up lowerbitsets. http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150316/266951.html llvm-svn: 232769
