Don't assume that pointer and cell size are identical, part 1

Browse Source 
On ppc64, cell size is 32 bits but pointers are 64-bit.
Thus, direct casts result in warnings, treated as errors.

Use [u]intptr_t cast or cell2pointer and pointer2cell macros as necessary.

v2:
* Drop changes related to physical addresses since physical addresses may be
  wider than pointers (e.g., 36 bits on sparc32, as pointed out by Blue).
* Drop changes to cell2pointer() and pointer2cell() for now.
