Set maximum length of FixedArray in terms of elements instead an absolute number of bytes.

Browse Source 
This sets the limit to 128M elements on all platforms. Before allocating a large array may
cause an OutOfMemory on x64 whereas it would not on ia32.

Also remove an unused constant from the FreeSpace class.
