produce it. This adds a function to the TargetMachine that produces this analysis via a callback for each function. This in turn faves the way to produce a *different* TTI per-function with the correct subtarget cached. I've also done the necessary wiring in the opt tool to thread the target machine down and make it available to the pass registry so that we can construct this analysis from a target machine when available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227721 91177308-0d34-0410-b5e6-96231b3b80d8
