Summary:  
Add the following strength reduction and 'X' detection 
functions to NUMERIC_STD (and similarly NUMERIC_BIT). 

Detail:
    FUNCTION To_X01 ( s : UNSIGNED ) RETURN UNSIGNED; 
    FUNCTION To_X01 ( s : SIGNED ) RETURN SIGNED; 

    FUNCTION To_X01Z ( s : UNSIGNED ) RETURN UNSIGNED; 
    FUNCTION To_X01Z ( s : SIGNED ) RETURN SIGNED; 

    FUNCTION To_UX01 ( s : UNSIGNED ) RETURN UNSIGNED; 
    FUNCTION To_UX01 ( s : SIGNED ) RETURN SIGNED; 

    FUNCTION Is_X ( s : UNSIGNED ) RETURN BOOLEAN; 
    FUNCTION Is_X ( s : SIGNED ) RETURN BOOLEAN;
