Ability to hide Microsoft clear button on input

[MKuenzi]

I am implementing a paper-input with a clear button, but of course this looks funny when you have my component open in IE which also has it's own clear button. I am not sure of the correct way the team would like to solve this but if I had the ability to hide the clear button in IE I would be very happy.

Could be fixed with something simple as a selector, or perhaps just add a mixin or variable so you do not break anyone who likes the fact IE does this....
