'int' is enough for 'length' to migrate code from x86 to x64

I don't think I have ever written a D program where an array had more than 
2^^31 elements.  And I'm sure I've never had it where 2^31-1 wasn't enough 
and yet 2^^32-1 was.

Zero, on the other hand, is usually quite near the typical array lengths and 
differences in lengths.
