1464 – "static" foreach breaks CTFE

The following code gives compile-time error, "cannot evaluate gen() at compile time." Removing the "i" from the foreach fixes this.
template Tuple(T...)
{
	alias T val;
}
alias Tuple!(int) Tup;
string gen()
{
 foreach (i, type; Tup.val)
 {
 }
 return null;
}
string text = gen();

It's aliasing the template instantiation, not the tuple. It should 
compile in 1.x as well as 2.x.

Fixed dmd 1.021 and 2.004
