Proposed patch

Testcase:

void main()
{
    int a = cast(int)null;
}

DMD 1.046 compiles fine.
DMD 1.047 outputs: 
test.d(3): Error: Integer constant expression expected instead of null
test.d(3): Error: Integer constant expression expected instead of null

Attaching proposed patch (needs review).
