Patch (DMD 2.030)

The current declaration syntax does not handle a qualified type with an
intermediate segment which does tuple indexing.

For example, the following does not compile:
--------------------
import std.typetuple;
template Trait(alias v) { alias typeof(v) Type; }
alias TypeTuple!(Trait!(42)) List;
List[0].Type var; // -> "no identifier for declarator List[0]"
--------------------
The compiler cannot parse "List[0].Type" as a type.

The attached patch enables the compiler to handle such intermediate tuple
indexing with a slight change to the BasicType2 syntax:
--------------------
BasicType2:
        *
        [ ]
        [ Expression ]
        [ Expression .. Expression ]
        [ Type ]
        delegate Parameters FunctionAttributes_opt
        function Parameters FunctionAttributes_opt
        . IdentifierList    // !! Add this
--------------------
