mpi: bug in range test predictes.
* mpi/mpi.c (mp_in_range, s_mp_in_big_range): The ptrnd
calculation here is wrong; it adds together dissimilar units:
bits and bytes. In the case of mp_in_range, we are okay by
fluke, because the calculation works out to 1 anyway. We would
not be okay of a mp_digit was half the size of a pointer.
In s_mp_in_big_range we have a problem. On 32 bit platforms,
ptrnd is wrongly calculated as 1 rather than 2, and so values
perfectly in range are rejected.
