There are two nontrivial details here: * Loop structure update interface is quite different with new pass manager, so the code to add new loops was factored out * BranchProbabilityInfo is not a loop analysis, so it can not be just getResult'ed from within the loop pass. It cant even be queried through getCachedResult as LoopCanonicalization sequence (e.g. LoopSimplify) might invalidate BPI results. Complete solution for BPI will likely take some time to discuss and figure out, so for now this was partially solved by making BPI optional in IRCE (skipping a couple of profitability checks if it is absent). Most of the IRCE tests got their corresponding new-pass-manager variant enabled. Only two of them depend on BPI, both marked with TODO, to be turned on when BPI starts being available for loop passes.
