Drop maskmove intrinsic, not portable. Its implicit NT hint may also hurt performance.
Make the tables endian-agnostic.

Mind checking if its possible to improve some SPU instructions too? Such as FCGT/FNMS as those are the most commonly used by games. Improving performance on those will for sure help a lot of titles even if it's just a little. |

Please test with clear cache. Old SSE2 masked store has implicit non-temporal hint which may kill performance if misused.
