    xtensa_saveusercontext:Leave the context information empty
    
    In the current implementation of other architectures, it is not really 
implemented to preserve the context, so it is emulated from other architectures 
to clear the context.
    If this behavior is not implemented, it will cause the xtensa architecture 
processor to loop assert in the active assert case
