Loads and stores can have different pipeline behavior, especially on embedded chips. This change allows those differences to be expressed. Except for the 440 scheduler, there are no functionality changes. On the 440, the latency adjustment is only by one cycle, and so this probably does not affect much. Nevertheless, it will make a larger difference in the future and this removes a FIXME from the 440 itin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153821 91177308-0d34-0410-b5e6-96231b3b80d8
