bifrost: Simplify derivatives a bit

Instead of two magic ternary operations, define a new `axis` temporary
which is 1 for X and 2 for Y.  Then define everything else in terms of
this variable.  In particular, the mask operation we do on LANE_ID is a
mask so it makes more sense to use ~axis than 1/2 but in the other
order.
