Qualifiers can now be streamed into the DiagnosticEngine using
regular << operator. If Qualifiers are empty 'unqualified' will
be printed in the diagnostic otherwise regular qual syntax is
used.

GCC and Clang both do not warn on:
struct a { virtual void func(); };
struct b: a { virtual void func(); void func(int); };
struct c: b { void func(int); using b::func; };
but if the "using" was using a::func GCC would still remain silent where Clang
would warn. This change makes Clang consistent with GCC's existing behavior.

The difference with gcc is that it warns if you overload virtual methods only if
the method doesn't also override any method. This is to cut down on the number of warnings
and make it more useful like reported here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20423.
If we want to warn that not all overloads are overriden we can have an additional
warning like -Wpartial-override.
-Woverloaded-virtual, unlike gcc, is added to -Wmost. Addresses rdar://8757630.
