(New_Overloaded_Entity.Check_Conforming_Paramters): Add new
Conformance_Type parameter. With the value of
Subtype_Conformant, the behavior of Check_Conforming_Parameters
is unchanged. The call in Matching_Entry_Or_Subprogram to
instead passes in Type_Conformant. This corresponds to the use
of "type conformant" in Ada RM 9.4(11.4/3).
(New_Overloaded_Entity.Has_Matching_Entry_Or_Subprogram): Add
new Normalized_First_Parameter_Type function to help in ignoring
the distinction between protected and access-to-protected first
parameters when checking prefixed-view profile matching. Replace
computations of the type of the first parameter with calls to
this function as appropriate.
