Qualcom's new core, oryon-1, has a different characteristics for memset than the current versions of memset. For non-zero, larger sizes, using GPRs rather than the SIMD stores is ~30% faster. For even larger sizes, using the nontemporal stores is needed not to polute the L1/L2 caches. For zero values, using `dc zva` should be used. Since we know the size will always be 64 bytes, we don't need to figure out the size there. I started with the emag memset and added back the `dc zva` code.
