Alexey Bataev 27d3528acf [SLP]Fix vectorization of insertelements with multiple uses. 
SLP vectorizer should not consider in sertelements with multiple uses as
a part of high level build vector, it must be considered as
a terminating insertelement in the vector build, otherwise it may
produce incorrect code.
