This optimizes tiling set eviction queue not to look for RFA tiles in pending
tree having priority bin EVENTUALLY or SOON (because those tiles cannot be RFA).

0.7 % for layer_eviction_tile_iterator_construct_and_iterate and for
layer_eviction_tile_iterator_construct,
0.2 % for tile_manager_eviction_tile_queue_construct and for
tile_manager_eviction_tile_queue_construct_and_iterate,
on average.
