See compute_frame_size for details about the frame layout.
??? If flag_profile_values is true, and we are generating 32-bit code, then
we assume that we will need 16 bytes of argument space. This is because
the value profiling code may emit calls to cmpdi2 in leaf functions.
Without this hack, the local variables will start at sp+8 and the gp save
area will be at sp+16, and thus they will overlap. compute_frame_size is
OK because it uses STARTING_FRAME_OFFSET to compute cprestore_size, which
will end up as 24 instead of 8. This won't be needed if profiling code is
inserted before virtual register instantiation. */
