  -----------
  [MIR] Serialize MachineFrameInfo::isCalleeSavedInfoValid() (#90561)

In case of functions without a stack frame no "stack" field is
serialized into MIR which leads to isCalleeSavedInfoValid being false
when reading a MIR file back in. To fix this we should serialize
MachineFrameInfo::isCalleeSavedInfoValid() into MIR.
