[Ada] Incorrect Dynamic_Predicate results for static arguments
gcc/ada/ * exp_ch6.adb (Can_Fold_Predicate_Call): Do not attempt folding if there is more than one predicate involved. Recall that predicate aspect specification are additive, not overriding, and that there are three different predicate aspects (Dynamic_Predicate, Static_Predicate, and the GNAT-defined Predicate aspect). These various ways of introducing multiple predicates are all checked for. A new nested function, Augments_Other_Dynamic_Predicate, is introduced. * sem_ch4.adb (Analyze_Indexed_Component_Form.Process_Function_Call): When determining whether a name like "X (Some_Discrete_Type)" might be interpreted as a slice, the answer should be "no" if the type/subtype name denotes the current instance of type/subtype.
