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

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added a comment.

This LGTM too, just adding mtcw wondering if these extra checks for more accurate reporting are worth placing under allowExtraAnalysis(); and/or if TLI->isFunctionVectorizable() shouldn't be the one informing the cause of its failure when returning false.
