Clean up RenderWidget::destroy() to share more code

[Simon Fraser (smfr)]

RenderWidget::destroy() has comments about not sharing more code with other classes. This needs cleaning up. It's a PITA to add code here.

Looks great, just one question.

> Source/WebCore/rendering/RenderWidget.cpp:-142
> -    if (hasOverrideSize())
> -        setOverrideSize(-1);

this is different from what RenderBox::destroy() did, it did:
gOverrideSizeMap->remove(this)

are these equivalent?

[Simon Fraser (smfr)]

Almost:

void RenderBox::setOverrideSize(int s)
{
    if (s == -1) {
        if (hasOverrideSize()) {
            setHasOverrideSize(false);
            gOverrideSizeMap->remove(this);
        }

I'll change RenderBox::willBeDestroyed() to call setOverrideSize(-1);
