[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 bug59;

void main()
{
    int[2] a = 0;
    //func(a);
    a[0] = 1;
    int i = a[0];
    int* p = &a[0];
}

void func(int[2] a)
{
    int* p = cast(int*)a;
}

void func2(int[4] a)
{
    int* p = 3+cast(int*)a;
}
