[SystemZ] Extend memcpy and memset support to all constant lengths Lengths up to a certain threshold (currently 6 * 256) use a series of MVCs. Lengths above that threshold use a loop to handle X*256 bytes followed by a single MVC to handle the excess (if any). This loop will also be needed in future when support for variable lengths is added. Because the same tablegen classes are used to define MVC and CLC, the patch also has the side-effect of defining a pseudo loop instruction for CLC. That instruction isn't used yet (and wouldn't be handled correctly if it were). I'm planning to use it soon though. llvm-svn: 189331
