/* Why 16?
Because some CPUs need alignment, for example SSE2 on P4, & most RISC CPUs
it will just trigger an exception and the unaligned load will be done in the
exception handler or it will just segfault (SSE2 on P4).

For AVX ASM. SSE / NEON needs only 16.
Why not larger? Because I did not see a difference in benchmarks ...
