[PATCH] D30262: [SLP] Fix for PR32036: Vectorized horizontal reduction returning wrong result

[Alexey Bataev via Phabricator via llvm-commits]

ABataev created this revision.

If the same value is used several times as an extra value, SLP
vectorizer takes it into account only once instead of actual number of
using.
