ARM: Default to using optimized memset and memcpy routines
We have long had available optimized versions of the memset and memcpy functions that are borrowed from the Linux kernel. We should use these in normal conditions as the speed wins in many workflows outweigh the relatively minor size increase. However, we have a number of places where we're simply too close to size limits in SPL and must be able to make the size vs performance trade-off in those cases.
