[Bug 11557] Authors should not be allowed to specify roles on elements that they already have by default

<button role=button aria-pressed=true> should not do anything different than
<button aria-pressed=true> according to the ARIA spec as far as I can tell
(that's what the "implicit semantics" stuff is all about!). If it does, ARIA
should be fixed.
