Speed up jqueryui/position $.support check for old IE
Speed up jqueryui/position $.support check for old IE

This feature detection would only ever return true for Old IE, but
Running it causes a “Recalculate Style” forced reflow to be ran. That
Is slow. So hardcoding it will speed things up

Test plan:
* nothing should actually change but pages should load a little faster
