[PATCH] D38693: [SLP] Consider extractelements as shuffles iff they have the same type/parent etc.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev created this revision.

We may try to treat set of extractelements as the shuffle wrongly if
they have different parents|types, are used in real gather tree entries
etc. Patch fixes this problem.
