__xdtor() also calls the __dtor() that are mixed with template mixins while __dtor() only call the __dtor() that matches to the normal ~this(){}

Nice example that speaks by itself:

=================
int i;
struct Foo
{
    template ToMix(){ ~this(){++++i;}}
    ~this(){++i;}
    mixin ToMix;
}

void main()
{
    Foo* foo = new Foo;
    foo.__xdtor;
    assert(i==3);
    Foo* other = new Foo;
    foo.__dtor;
    assert(i==4); // and not 6 ;)
}
