vc4: Compile the LT image helper per cpp we might load/store.
For the partial load/store support I'm about to add, we want the memcpy to
be compiled out to a single load/store. This should also eliminate the
calls to vc4_utile_width/height().
Improves x11perf -putimage100 performance by 3.76344% +/- 1.16978% (n=15)
