Patch by Tim Volodine <timvolodine@chromium.org> on 2012-12-19
Reviewed by Kenneth Rohde Christiansen.

Source/WebCore:

Disallow autosizing of form input controls like buttons, text input fields, selection controls, radio buttons
and check boxes. This is a short term solution to avoid inconsistent autosizing of form controls (which is
worse than not autosizing at all).
