Add Guard for invalid readyState in IE9 and IE10

IE9 and IE10 can get into a state where 

document.readyState === "interactive" // => true

even though the document is not yet ready. This happens
when a script tag is added dynamically to A dom (can
be detached fragment) and completes loading. I will look
through for the tests to add.
Support loaded readyState in IE9, IE10

loaded should still be safe so this should allow the check to work for
that case as well as requiring that IE9 and IE10 interactive are ignored.
