Add a ARM specific pre-allocation pass that re-schedule loads / stores from consecutive addresses togther. This makes it easier for the post-allocation pass to form ldm / stm. This is step 1. We are still missing a lot of ldm / stm opportunities because of register allocation are not done in the desired order. More enhancements coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73291 91177308-0d34-0410-b5e6-96231b3b80d8
