        Test: fast/css/input-search-padding.html

        An <input type="search"> contains an inner block, which is explicitly
        centered in RenderTextControlSingleLine based on the height of the element.
        However, the clipping rect was not using the set location, and instead
        calculated off of the top border and padding alone. This also vertically
        centers the Caps Lock indicator.

        * rendering/RenderTextControl.cpp: moved controlClipRect implementation to RenderTextControlSingleLine
        * rendering/RenderTextControl.h: allow a subclass implementation of controlClipRect, removed redundant hasControlClip implementation, and moved controlClipRect
        * rendering/RenderTextControlSingleLine.cpp:
        (WebCore::RenderTextControlSingleLine::paint): vertically center the Caps Lock indicator
        (WebCore::RenderTextControlSingleLine::controlClipRect): use the set location of the anonymous inner block instead
        * rendering/RenderTextControlSingleLine.h: allow for an implementation of controlClipRect for <input type="search">
