Naively, by 'vectorization-friendly' I mean a rewrite of the trivial loops
encoding explicitly the specified semantics (see, for example the 2nd
difficulty pointed out by Jakub). If we find a way to do that effectively but
still abstracting from the detail of the vector instructions, seems a great
idea! Does something similar already exist?
