SBC arrays and constant tables aligned at 16 byte boundary for SIMD
Most SIMD instruction sets benefit from data being naturally aligned.
And even if it is not strictly required, performance is usually better
with the aligned data. ARM NEON and SSE2 have different instruction
variants for aligned/unaligned memory accesses.
