CoroCleanup was running SimplifyCFG in a separate function pass manager before invalidating analyses.

InstCombine wasn't seeing that LibCallSimplifier::optimizeSinCosPi() modified the IR because it always returns nullptr due to the way it optimizes multiple calls at once. There's likely a better way of fixing this.

Move PreservedAnalysisChecker further down StandardInstrumentations so other Instrumentations (e.g. printing) have a chance to run before PreservedAnalysisChecker crashes.
