Should we do this in LexicallyOrderedRecursiveASTVisitor?

There are some other cases with CXXOperatorCallExpr where the order needs to be changed, e.g. postfix operators, operator->, operator() and operator[].
It can be done by sorting by SourceLocation of the first two elements, as the operator is always the first one.
