    [cc2-qbe] Small stetic changes to the output of qbe
    
    After this commit we have a beatitul output for something like
    
    $ cc1 | cc2
    int
    func(int a, int b)
    {
            int c;
    
            c = a + c;
    }
    ^D
    export function h $func(h %a,h %b)
            %c h= alloc2 2
            $.1 w= load %a
            $.2 w= load %c
            $.3 w= add $.1,$.2
                    storew $.3,%c
    }
