lieu of 'Size of the expression to compute the expression's size.

* exp_ch3.adb (Make_Allocator_For_Return): Put back an interface
conversion for expressions with non-interface class-wide type.
2023-01-16 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch3.adb (Expand_N_Object_Declaration): Also optimize aliased
objects if their nominal subtype is not an unconstrained array.
2023-01-16 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch3.adb (Expand_N_Object_Declaration): Factor out conditions
needed for an initializating expression that is a function call to
be renamable into the Is_Renamable_Function_Call predicate.
Use it to implement the renaming in the case of class-wide interface
objects. Remove an interface conversion on all paths, separate and
optimize the renaming path in the special expansion for interfaces.
(Is_Renamable_Function_Call): New predicate.
(Make_Allocator_For_Return): Put back an interface conversion.
* exp_ch6.adb (Apply_CW_Accessibility_Check): Remove useless access
checks on RE_Tag_Ptr.
