LoopVectorizer: Recognize min/max reductions
A min/max operation is represented by a select(cmp(lt/le/gt/ge, X, Y), X, Y) sequence in LLVM. If we see such a sequence we can treat it just as any other commutative binary instruction and reduce it. This appears to help bzip2 by about 1.5% on an imac12,2. radar://12960601 llvm-svn: 179773
