[PATCH] D76623: [VectorCombine] try to form a better extractelement

[Roman Lebedev via Phabricator via llvm-commits]

While this looks good in principle, i'm starting to have second thoughts about the general design here..

Since this doesn't affect the calculated cost, i wonder if it would be better to go more generic,
and instead implement some kind of lane reordering?
