<https://webkit.org/b/124338> Source/WebCore: Turn FontDescription::m_families into a RefCountedArray<AtomicString> instead of a Vector<AtomicString, 1>. This allows FontDescription to share the families list between copies, instead of each object having its own Vector. Also, FontDescription itself shrinks by 16 bytes. Reviewed by Antti Koivisto. Source/WTF: Add RefCountedArray::operator==. Reviewed by Antti Koivisto. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@159279 268f45cc-cd09-0410-ab3c-d52691b4dbfc
