b4db85c8c3 don't erase ptr type early when construction a Cons HeapCellValue 
rather than passing an address as usize pass the ArenaHeader pointer
similarly don't return a u8 ptr but use a ArenaHeader pointer instead

Don't convert the pointer to a ConsPtr by going through native endian
bytes in between.
We are exploiting the fact that the 3 least significant bytes are zero
for pointer to types of alignment 8 and we expect these to line up with
the f, m, and tag field at the end of the ConsPtr struct, but using
native endiannes for this would only work on big endian systems.

ff293a56e6 fix large enum variant size difference warning of PermVarAllocation 
by wrapping BranchNumber in an Arc.
PermVarAllocation::Done had size 208 and is now down to 32.
A Box rather than an Arc would be smaller, but it looks like BranchNumber/BranchDesignator are clones a bunch so I expect it to be beneficial to reduce allocations both of the Box itself as well as its content.

5fc21241d6 hint to the compiler/branch-predictor that 
we expect p to be in bound

if we are suffiently certain that p can never be oob
unsafe get_unchecked could be used to
eliminate bounds checking all together
which should improve performance further.

8aab887388 switch from Integer to u128 
- u128 is only 16 bytes instead of 24
- incrementing u128 does not involve heap allocations
- u128 should be sufficent
 it would take more than 2 sextilion years to overflow if we would be incrementing it every tick at 5GHz
   i.e. 2^128-1 / 5 GHz / 60 / 60 / 24 / 356 > 2 sextilion

before this ~3.2% of the execution time of the program in https://github.com/mthom/scryer-prolog/issues/3265#issuecomment-4103176469 was spend in the increment_call_count function, after this change it's down to 0.3%
