This just identifies the intrinsics as candidates for vectorization. It does not mean we will attempt to vectorize under normal conditions (the test file is forcing vectorization). The cost model must be fixed to show that the transform is profitable in general. Allowing vectorization with these intrinsics is required to avoid potential regressions from canonicalizing to the intrinsics from generic IR: https://bugs.llvm.org/show_bug.cgi?id=37417 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@346661 91177308-0d34-0410-b5e6-96231b3b80d8
