[PATCH] D60790: [LPM/BPI] Preserve BPI through trivial loop pass pipeline

[Hal Finkel via Phabricator via llvm-commits]

hfinkel added a comment.

Can you please take the rationale, especially for LoopSimplify, and add it as a comment in the source code? At some point someone might break this invariant, and without the comment, they'll be no easy way to know that.
