CGSCC pass manager. This should insulate the inlining decisions from the vectorization decisions, however it may have both compile time and code size problems so it is just an experimental option right now. Adding this based on a discussion with Arnold and it seems at least worth having this flag for us to both run some experiments to see if this strategy is workable. It may solve some of the regressions seen with the loop vectorizer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184698 91177308-0d34-0410-b5e6-96231b3b80d8
