[PATCH] [SLPVectorization] Vectorize Reduction Chain feeding into a 'return' statement

[Arnold Schwaighofer]

The code looks fine to me.

There could be a benefit in calling:

 SLPVectorizer::tryToVectorize(BinaryOperator *V, BoUpSLP &R) 

instead of directly calling tryToVectorizePair.

Did you run performance tests  (test-suite) on x86 or arm?

Thanks for working on this!
