Make use of image flags in mmx and sse2 iterators

Browse Source 
Now that we have the full image flags available, the SSE2 and MMX
iterators can simply check against SAMPLES_COVER_CLIP_NEAREST (which
is computed in pixman_image_composite32()) instead of comparing all
the x/y/width/height parameters.
