[MachineScheduler]Add support for store clustering Perform store clustering just like load clustering. This change add StoreClusterMutation in machine-scheduler. To control StoreClusterMutation, added enableClusterStores() in TargetInstrInfo.h. This is enabled only on AArch64 for now. This change also add support for unscaled stores which were not handled in getMemOpBaseRegImmOfs(). llvm-svn: 266437

CodeGen: Rename DEBUG_TYPE to match passnames Rename the DEBUG_TYPE to match the names of corresponding passes where it makes sense. Also establish the pattern of simply referencing DEBUG_TYPE instead of repeating the passname where possible. llvm-svn: 303921

[MachineScheduler]Add support for store clustering Perform store clustering just like load clustering. This change add StoreClusterMutation in machine-scheduler. To control StoreClusterMutation, added enableClusterStores() in TargetInstrInfo.h. This is enabled only on AArch64 for now. This change also add support for unscaled stores which were not handled in getMemOpBaseRegImmOfs(). llvm-svn: 266437
