[PATCH] D107240: [LLVM][NFC] Make multiple bitwise MathExtras functions constexpr

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I copied a chunk of this patch to godbolt and added two different constexpr usages of countLeadingZeros that both fail with MSVC https://godbolt.org/z/Maen4bac4 I'm guessing that because everything is a template, MSVC doesn't diagnose anything until you try to use it in constexpr context.
