tables: Restore the warp filter table order for architectures other than x86
This effectively reverts a0692eb8ef38 for other architectures. The
order that is beneficial for x86 SIMD is not beneficial for other
architectures.
For a NEON implementation of the warp filter, reordering the filter
coefficients back in the right order took 1/4 of the filter runtime.
