[PATCH] D56551: [LoopVectorizer] give more advice in remark about failure to vectorize call

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Can we check whether the function could be vectorized if fast math were enabled, so we only show the advice when it's relevant?

"relaxing the floating-point model" is a little confusing... can we explicitly say "consider turning on fast math" or something like that?
