[cfe-dev] a patch for static analyzer to check : std::list::empty()

[彩云追月]

Hello, 
    recently, as an exercise, I have implemented a checker for clang static analyzer.It checks the call of std::list::size( ) .


    It is more efficient to use containers empty() method to identify an empty container.Codes like bellow :


    int f() {
        list<int> l;
        if (l.empty() == 0) {
        }
     }    
    will be warned.


 btw, I  did my dev on the release 3.5.
