This provides a place to add customized operation cost information and control some other target-specific IR-level transformations. The only non-trivial logic in this checkin assigns a higher cost to unaligned loads and stores (covered by the included test case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173520 91177308-0d34-0410-b5e6-96231b3b80d8
