FWIW, I think that even if the specific flang issue is no longer present due to source changes in flang, we shouldn't re-enable this pass without some analysis for why that compile-time explosion happened in LLVM terms, and mitigation to avoid it -- beyond just lowering the threshold to avoid specific examples. It seems plausible that it could still happen in other cases with the lowered threshold.
