[MIPS] Fast android_memset for Mips64, Mipsr6 Fix broken mips64 build by replacing mips32r2-only android_memset.S. Use HW-bonded pairs of 64-bit stores to fill 128 bits/cycle. Rely on HW automatic cache prefetch optimizations. Software cache prefetching is counterproductive on next mips cores. New method is coded in C, and also works okay on non-Mips architectures.
