[PATCH] D67300: [ConstantFolding] Fold constant calls to log2()

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I'm not really happy with adding more uses of ConstantFoldFP/ConstantFoldBinaryFP; they're flawed because they produce results that depend on the host's libm implementation.  But I guess there isn't any reason to support log and not log2.
