Extend test for better coverage.
Without this change nothing was covering this addFrameMove:
// For 64-bit SVR4 when we have spilled CRs, the spill location
// is SP+8, not a frame-relative slot.
if (Subtarget.isSVR4ABI()
&& Subtarget.isPPC64()
&& (PPC::CR2 <= Reg && Reg <= PPC::CR4)) {
MachineLocation CSDst(PPC::X1, 8);
MachineLocation CSSrc(PPC::CR2);
MMI.addFrameMove(Label, CSDst, CSSrc);
continue;
}
