This computes DominatorTree, LoopInfo, BPI and BFI for *every callsite* that is considered for inlining. Even though this is (I assume) turned off by default, it's still very expensive. Even in the new PM, this can be avoided only by incrementally updating the BFI of the caller after inlining a callee into it.
