[svn r349] Fixed problems with static arrays of void as well as a static arrays with zero length. Fixed issues with DMD generated assert statements when using class invariants, generally due to incomplete ASTs. Removed some dead code. Added a few comments.

int func(int a, int b)
{
    if (a == b)
        return 0;
    else if (a < b)
        return -1;
    else
        return 1;
}

void main()
{
    int i = func(3,4);
    assert(i == -1);
}
