I made some cosmetic changes to this and committed it.  AFAICT,
there's no measurable performance change to the "numeric" regression
test, but I got a solid 45% speedup on "numeric_big", so it's
clearly a win for wider arithmetic cases.

It seemed to me to be useful to actually rename CFLAGS_VECTOR
if we're changing its meaning, so I made it CFLAGS_VECTORIZE.
