Hugo Holgersson 142ae0cdf9 Clang: Add semantic C++ operator-token styling ...

We used to style overloaded operators in the same way
as C++'s built-in operators. There was no way to tell
if a + token would call a operator+() function or not.

Now, if an operator is overloaded (redefined),
we give it the "Overloaded Operator"-mixin so users
can style it differently.

Note: Calls to overloaded 'new' and 'delete' are not
highlighted by "Overloaded Operator". This is because
clang today always maps these to CXCursor_CXXNewExpr
and CXCursor_CXXDeleteExpr with cursor.spelling == ""
(empty string). So there is no (?) quick way for us
to tell if a new/delete-token was overloaded or not.

After follow-ups, follow symbol will work for operator
overload usages in current translation unit.
