* exp_attr.adb (Enclosing_Object): New function local to handling of
access attributes,
for retrieving the innermost enclosing object prefix of a compound name.
(Expand_N_Attribute_Reference, N_Attribute_Access): In the case where an
Access attribute has a prefix that is a dereference of an access
parameter (or the prefix is a subcomponent selected from such a
dereference), apply an accessibility check to the access parameter.
Replaces code that rewrote the prefix as a type conversion (and that
didn't handle subcomponent cases).
Also, this is now only applied in the case of 'Access.
* exp_ch6.adb (Expand_Call): Add handling for the case of an access
discriminant passed as an actual to an access formal, passing the
Object_Access_Level of the object containing the access discriminant.
