On looking at rs6000_aix64_reg_offsets, I noticed that xer_offset is
not a multiple of 8. Apparently, AIX uses a 32-bit field for cr, xer,
and fpscr. So it looks like I can't use gpr_size for any of these
registers in ppc_{supply,collect}_gregset. Mind you, aix 64-bit gdb
is broken anyway due to these functions assuming the gprs were
32-bit.
