It broke the !ENABLE(CSS_REGIONS) builds, for example on the Qt minimal bot:

/ramdisk/qt-linux-release-minimal/build/WebKitBuild/Release/Source/WebCore//.obj/release-shared/dom/Element.o:(.data.rel.ro._ZTVN7WebCore7ElementE[vtable for WebCore::Element]+0x20c): undefined reference to `WebCore::Element::shouldMoveToFlowThread(WebCore::RenderStyle*) const'
/ramdisk/qt-linux-release-minimal/build/WebKitBuild/Release/Source/WebCore//.obj/release-shared/dom/StyledElement.o:(.data.rel.ro._ZTVN7WebCore13StyledElementE[vtable for WebCore::StyledElement]+0x20c): undefined reference to `WebCore::Element::shouldMoveToFlowThread(WebCore::RenderStyle*) const'

/ramdisk/qt-linux-release-minimal/build/WebKitBuild/Release/Source/WebCore//.obj/release-shared/html/HTMLAnchorElement.o:(.data.rel.ro._ZTVN7WebCore17HTMLAnchorElementE[vtable for WebCore::HTMLAnchorElement]+0x20c): undefined reference to `WebCore::Element::shouldMoveToFlowThread(WebCore::RenderStyle*) const'
/ramdisk/qt-linux-release-minimal/build/WebKitBuild/Release/Source/WebCore//.obj/release-shared/html/HTMLAppletElement.o:(.data.rel.ro._ZTVN7WebCore17HTMLAppletElementE[vtable for WebCore::HTMLAppletElement]+0x20c): undefined reference to `WebCore::Element::shouldMoveToFlowThread(WebCore::RenderStyle*) const'
/ramdisk/qt-linux-release-minimal/build/WebKitBuild/Release/Source/WebCore//.obj/release-shared/html/HTMLAreaElement.o:(.data.rel.ro._ZTVN7WebCore15HTMLAreaElementE[vtable for WebCore::HTMLAreaElement]+0x20c): more undefined references to `WebCore::Element::shouldMoveToFlowThread(WebCore::RenderStyle*) const' follow

The problem is that Element::shouldMoveToFlowThread(...) is defined inside
ENABLE(CSS_REGIONS) guard, but used outside the same guard. Could you fix
it, please?

I think the entire content of this method should be under guard. If !ENABLE(CSS_REGIONS) it should just return false.

@Zoltan Thanks for fixing this, you were faster than me :)
