[PowerPC] Create a FixedStack object for CR save in linkage area.
hasReservedSpillSlot returns a dummy frame index of '0' on PPC64 for the
non-volatile condition registers, which leads to the CalleSavedInfo
either referencing an unrelated stack object, or an invalid object if
there are no stack objects. The latter case causes the mir-printer to
crash due to assertions that checks if the frame index referenced by a
CalleeSavedInfo is valid.
To fix the problem create an immutable FixedStack object at the correct offset
in the linkage area of the previous stack frame (ie SP + positive offset).
