[PATCH] D148966: [SLP] Cleanup: Remove loop around `tryToVectorizeSequence` of PHIs.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added a comment.

Do not forget that instructions can mutate during vectorization and if at the first iteration they are not compatible, they might be transformed into extractelement instructions on this first iteration, and become compatible on the second one
