Restore cutil memsetX functions for Cortex-A9.

Restores usage of memset16/32 functions from Android's libcutil
library for platforms running Cortex-A9, since non-Neon
is usually faster.

Modify sample buffer size for larger displays.

Modifies the intermediate buffer size for sample pixel indexes, used in the
sample proc function calls. If the buffer is not large enough, the job is split
into several calls. This would impact the performance of SIMD optimizations.
