    ada: Avoid calling Resolve with Stand.Any_Fixed as the expected type
    
    When we call Resolve for an expression, we pass in the expected type
    for that expression. In the absence of semantic errors, that expected type
    should never be any of the "Any_xxx" types declared in stand.ads (e.g.,
    Any_Array, Any_Numeric, Any_Real). In particular, it should never be 
Any_Fixed.
    Fix a case in which this rule was being violated.
    
    gcc/ada/ChangeLog:
    
            * sem_res.adb
            (Set_Mixed_Mode_Operand): If we are about to call Resolve
            passing in Any_Fixed as the expected type, then instead pass in
            the fixed point type of the other operand (i.e., B_Typ).
