[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.

module staticvars;

int func()
{
    static int i;
    return i++;
}

void main()
{
    assert(func() == 0);
    assert(func() == 1);
}
