By default, boost the chain depth contribution of loads and stores. This will allow a load/store pair to vectorize even when it would not otherwise be long enough to satisfy the chain depth requirement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149761 91177308-0d34-0410-b5e6-96231b3b80d8
