[AArch64] Improve cost model to handle sdiv by a pow-of-two. This patch improves the target-specific cost model to better handle signed division by a power of two. The immediate result is that this enables the SLP vectorizer to do a better job. http://reviews.llvm.org/D5469 PR20714 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218607 91177308-0d34-0410-b5e6-96231b3b80d8
