(WebCore::RenderThemeQt::paintSearchFieldCancelButton):
(WebCore::RenderThemeQt::paintMediaSliderThumb):
Removed an ASSERT() because nullness of o->node() is already asserted.
* rendering/RenderInputSpeech.cpp:
(WebCore::RenderInputSpeech::paintInputFieldSpeechButton):
* rendering/RenderMediaControlsChromium.cpp:
(WebCore::paintMediaSliderThumb):
Passing shadowHost() to toParentMediaElement(), which accepts 0 and will return 0.
(WebCore::paintMediaVolumeSliderThumb): ditto.

* rendering/RenderThemeMac.mm:
(WebCore::RenderThemeMac::paintSearchFieldCancelButton):
Remove an ASSERT(input) because input never be null unless o->node() is
null. If o->node() is null, this function crashes.
(WebCore::RenderThemeMac::paintSearchFieldResultsDecoration):
(WebCore::RenderThemeMac::paintSearchFieldResultsButton):
(WebCore::RenderThemeMac::paintMediaMuteButton):
It's ok to ignore "node is a media element" case because this function
works only if node->isMediaControlElement().
(WebCore::RenderThemeMac::paintMediaPlayButton): ditto.
(WebCore::RenderThemeMac::paintMediaSliderTrack): ditto.
* rendering/RenderThemeSafari.cpp:
(WebCore::RenderThemeSafari::paintSearchFieldCancelButton):
Remove an ASSERT(input) because input never be null unless o->node() is
null. If o->node() is null, this function crashes.
