nir: split out lower_sub from lower_negate

Originally you had to have one or the other.  But actually I don't want
either.  (Or rather I want whatever is the minimum # of instructions.)

TODO: not sure where the best place to insert a check that driver hasn't
set *both* lower_negate and lower_sub?
