An, My comment #21 was confusing.  I meant that non-iOS platforms didn't support indeterminate radio buttons because they didn't support indeterminate appearance.  It didn't mean we didn't need to support HTMLInputELement::indeterminate in non-checkbox types.

- We need to support HTMLInputELement::indeterminate() and setIndetermiante() regardless of types.  This is defined by the standard and other browsers work so.
  So, We should remove !m_inputType->isCheckable() in HTMLInputElement::setIndetermiante().

- We don't need to support indeterminate radio button appearance except iOS.
 -- We should not return true from HTMLInputELement::isIndetermiante() except type=checkbox
 -- We don't need indeterminate-related code in RadioInputType.cpp

Additionally, we should not add branches by types like "if (isRadioButton())".  We should introduce InputType::supportsIndeterminateAppearance(), CheckboxInputType should return true for it, and RadioInputType should return true for it only on iOS.
