Improve IE8 performance

Leverage native qSA for more than just simple cases, perhaps first test for existence of non-CSS3 qSA and then regex the selector to see if it matches a broader range of non-CSS3 cases and can be handled by the native implementation. At the moment it's just tag and/or class (tag.class or .class) being given to qSA so performance is terrible across other common cases.

And, IE8 aint going away any time soon.
