Add sizeof_reg and new Machine configurations (#129)
Since the size of integer registers is not identical to the size of pointers
for the ppc64 and e5500 model the check for register pairs in
ExtendedAsm does not work correctly.
In order to avoid this a new field sizeof_intreg is introduced in the
Machine configuration which describes the size of integer registers.
New configurations for the ppc64 and e5500 model are added
and used.
