Change the heap reservation for 64-bit platforms.

Browse Source 
Hoard reserves a chunk of the address space to grow the heap into.
As there is a much larger address space available on 64-bit systems,
we may as well reserve a larger chunk of address space (64GB for now,
though could probably reserve a lot more than that and still leave
plenty of room for other areas).
