Don't print the entire declaration of the alliassee when `->toChars()` is called on an `AliasDeclaration`; just printing the name will do. This fixes #305, which otherwise tries to generate {{{ class E { void A() { alias /* recurse into E->toCBuffer() */ m; } } }}} by way of an infinite recursion (causing a segfault when the stack runs out).

module mini.norun_debug1;

void main()
{
    int* ptr;

    // all these should be inspectable
    int i = 1;
    int j = 2;
    long k = 3;
    float l = 4.521;
    ubyte m = 5;

    *ptr = 0;//cast(int)(i+j+k+l+m);
}
