[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 globals1;
extern(C) int printf(char*, ...);

char[] gstr = "hello world";

void main()
{
    printf("%.*s\n", gstr.length, gstr.ptr);
    char[] str = gstr;
    printf("%.*s\n", str.length, str.ptr);
}
