This code requires SLP to originate from loads, which seems to be a bit more
complicated than the currently implemented use-def scan (it will also need to
reduce/extract scalars from the vectors in the end of vector computation). I
don't see any major obstacles for this, however, currently I don't plan to work
on this.

Another required feature is to work on groups bigger than vectorization factor,
i.e., combining 2 statements in this example and leaving the 3rd one scalar.
