------- Additional Comments from zeng huiqing <huiqing.zeng at intel.com>
I have added an attachment to fix the bug:
1)in function HTMLInputElement::setChecked(...)
add "if(type()!=(InputTypeNames::checkbox()))' to avoid the unnecessary update
for checkbox".

2)in function HTMLInputElement::updateCheckedRadioButtons()
replace traversing document()->body() with Document::m_formElementsWithState to
improve the performance.
