...for the function passes. Since we don't need to run them in any specific order, we might as well run the function passes in the order that the callgraphsccpasses are being run in. If there is no CallGraphSCCPassBatcher active, the passmanager would check to see if there is a FunctionPassBatcher active, and if not it would create one. Finally, note that all of this behavior is specific to "Module PassManagers", so ideally none of the logic would be used/touched by the FunctionPassManager stuff etc. Given this, it shouldn't be in something generic like the base PassUnit c...

The patch below basically hammers out some ideas as to where I'd like to take the passmanager in LLVM.

As stated in the inliner improvements notes on your site, there seems to be a significant effect based on the order of application and traversal method used, wouldn't this hold true for other passes? I could be wrong, but this seems weird to me. This i...
