st/nine: Match REP implementation to LOOP

Previous implementation was behaving fine, but improve it by:
. Improved documentation
. Decreasing counter (comparing to 0 is likely to be faster than to constant)
. Move the counter update at the end for better performance for shaders that
break the loop earlier than when the count is done.
