r=me if you figure out how to make this work or compile it out on iOS

> Source/WebCore/html/shadow/TextControlInnerElements.cpp:176
> +    setAttribute(aria_labelAttr, AtomicString(AXSearchFieldCancelButtonText()));

iOS build failure:

html/shadow/TextControlInnerElements.cpp:176:47: error: use of undeclared identifier 'AXSearchFieldCancelButtonText'
    setAttribute(aria_labelAttr, AtomicString(AXSearchFieldCancelButtonText()));

That is in a !PLATFORM(IOS) block.

Separate question: Is the explicit AtomicString construction required here?

> Source/WebCore/html/shadow/TextControlInnerElements.cpp:201
> +        input->setValueForUser("");

Please use emptyString() rather than "".

Will add !PLATFORM(IOS)-guard around this code.

No, it is not required. Will remove.

Will substitute emptyString() for "".
