I've been looking at compilation time issues in the LICM pass, and it looks to me like colorEHFunclets() is probably being called a lot more often than it needs to be for functions that have Windows EH personality functions. For one thing, the funclet coloring is happening when computeLoopSafetyInfo() is called from LoopIdiomRecognize and LoopUnswitch but those passes don't use the coloring in...

I think the simplest, most complete, short term fix, would be to call llvm::colorEHFunclets, and to have the relevant instrumentation passes apply the appropriate funclet bundle when inserting function calls. It's not elegant because it means every simple instrumentation pass that inserts regular function calls (ASan, TSan, MSan, instrprof, etc) needs to be funclet-aware. But, it wil...

I think this is the same underlying issue as https://bugs.llvm.org/show_bug.cgi?id=40320. CCing Reid, who's had a bunch of thoughts on this in the past.
