	Add support for min/max reductions when "no-nans-float-math" is enabled. This allows us to assume we have ordered floating point math and treat ordered and unordered predicates equally. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181144 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-05	LoopVectorize: We don't need an identity element for min/max reductions	Arnold Schwaighofer
	We can just use the initial element that feeds the reduction. max(max(x, y), z) == max(max(x,y), max(x,z)) radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181141 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24	LoopVectorizer: Bail out if we don't have datalayout we need it	Arnold Schwaighofer

2013-04-18	LoopVectorizer: Recognize min/max reductions	Arnold Schwaighofer
	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179773 91177308-0d34-0410-b5e6-96231b3b80d8
