  Log Message:
  -----------
  [PowerPC][AIX] Update save/restore offset for frame and base pointers.

General purpose registers 30 and 31 are handled differently when they are
reserved as the base-pointer and frame-pointer respectively. This fixes the
offset of their fixed-stack objects when there are fpr calle-saved registers.
