Fix the default alignment of the allocations.
In order to enforce this constraint:
The pointer returned if the allocation succeeds shall be suitably
aligned so that it may be assigned to a pointer to any type of object
and then used to access such an object in the space allocated.
Force all allocations on 32 bit systems to have 8 byte alignment,
and all allocations on 64 bit systems to have 16 byte alignment.
Add a test to verify that the allocator returns the correct alignments.
