Instruction vcdgb is pretty expensive and will be typically slower than going
over memory. Only in those rare cases when you need the constant in your hot
path and the cache line holding your constant gets evicted between each
iteration, vcdgb might be faster (although even that is questionable and I
would like to have a look at a trace first). Therefore, I don't think this
would be beneficial.
