 * avoid excessive loads you have to accommodate a handful of 64-bit
 * values in the register bank and issue a bunch of shifts and mask.
 * It's a tradeoff: loads vs. shift and mask in big register bank[!].
 * On most CPUs eight single-byte loads are faster and I let other
 * ones to depend on smart compiler to fold byte loads if beneficial.
 * Hand-coded assembler would be another alternative:-)
