Looks like this causes a small compile-time regression: https://llvm-compile-time-tracker.com/compare.php?from=76ed4b1cec57ad26433e4808697d6c4d042d4b22&to=f2942b90778670d9ad974d025c779fc96afa737c&stat=instructions:u

It looks like this not only moves the code, but also changes the order of the checks -- it's possible that the new order is less optimal.
