Speed 4 still does not give a big gain over speed 3.
This just cleans it up a little from the last patch and comments
out features that do not seem to be giving much benefit.

This code serves no purpose in the re-factored sub 8x8 code.

Allow selective masking of individual split modes rather than
just a single on / off flag.

For speed 2 recovers the large speed loss seen for some derf
clips  in change Ie6bdfa0a370148dd60bd800961077f7e97e67dd4
and a small quality gain.

For speed 1 10 % speed increase observed locally on some derf clips
for minimal quality change.
