[PATCH] D128591: Transforms: Relax restrictions on pow(x, y) expansion

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

It seems problematic that LibCallSimplifier::optimizePow also folds pow ->powi yet we also have pow expansion code that is completely separate from powi (where its handled in CGP).

We now have TTI:isBeneficialToExpandPowI to decide when to expand powi intrinsics properly instead of hard coded limits like there are here.
