Title: Fix clearImmediate polyfill in IE10.

@hornairs @snookca

So, turns out, IE doesn't actually implement `clearImmediate`. `setImmediate`, sure, they invented it! But `clearImmediate`? I know, right?

This just moves around some of the logic to ensure that `clearImmediate` gets polyfilled if it doesn't exist.
