8.0-controls-scrum-418: up to 30% performance regression in Controls benchmarks

There are following regressions in build 8.0-controls-scrum-418 on Windows7-High-End machine:
 Controls.RadioButton: -29% (-28.80 fps)
 Controls.Checkbox: -31% (-30.42 fps)
 Controls.TableView-Mouse: 19% (-11.76 fps)


Steps to run Controls.Checkbox:
> cd JFX_WS/tests/performance/Controls/
> ant
> java -Djavafx.animation.fullspeed=true
       -cp "JFX_HOME/rt/lib/ext/jfxrt.jar;./dist/Controls.jar;../FXBenchmark/dist/FXBenchmark.jar;../../../import/benchmarks-2.1.1/benchmarks-2.1.1.jar"
       jrockit.bm.Main controls.bm.CheckboxBenchmark -i 1 -wt 0 -tr 60 -toggleStep 300


According to Hudson build #418 contains just one change:
- RT-28945: not enough to reset to initial value on slowpath, must also reset on fastpath if css set the current value (detail)

I will look at JPA profiles later today if I have time.
