- and fold the computations.

- * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>:
- Rename local variables. If the return Mechanism is By_Reference, pass
- return_by_invisible_ref_p to create_subprog_type instead of toggling
- TREE_ADDRESSABLE. Test return_by_invisible_ref_p in order to annotate
- the mechanism. Use regular return for contrained types with non-static
- size and return by invisible reference for unconstrained return types
- with default discriminants. Update comment.

- returns by invisible reference, turn the RESULT_DECL into a pointer.
- Do not handle DECL_BY_REF_P in the CICO case here.
- (call_to_gnu): Remove code handling return by target pointer. For a
- function call, if the return type has non-constant size, generate the
- assignment with an INIT_EXPR.
- (gnat_to_gnu) <N_Return_Statement>: Remove dead code in the CICO case.
- If the function returns by invisible reference, build the copy return
- operation manually.

- Adjust for renaming of macros. Copy the node only when necessary.
