IP_a, IP_b, IP_c, IP_d Memory Size Registers

As with the memory base address registers, the IP_a size register is also
used to control accesses to double size IP_ab and the IP_c size register is
used to control accesses to double size IP_cd.
The registers which control IP_c and IP_d are not used on the 200/300-
Series MVME172.
