Patch against dmd r680

Alias to a non-type tuple can't be used as a member of struct or class. The following code doesn't compile.
--------------------
struct Test(parameters_...)
{
    alias parameters_ parameters;
}
Test!(10, 20, 30) test;
static assert(typeof(test).parameters[1] == 20); // okay
static assert(       test .parameters[1] == 20); // (7)
--------------------
% dmd -o- -c test.d
test.d(7): Error: 10 is not a member
test.d(7): Error: static assert  ((__error) == (__error)) is false
--------------------

DotVarExp::semantic() only allows tuple of member variables as a member. The proposed patch changes it so that other kinds of tuples are allowed. Passed dmd/druntime/phobos tests.
