Declare NEW_EXPR local variable and attach the

(finalize_nrv): Add GNAT_RET parameter. Copy it into DATA. If the
function returns unconstrained, use finalize_nrv_unc_r as callback.

RET_OBJ is non-null.

* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: Adjust
call to components_to_record.
(components_to_record): Add FIRST_FREE_POS parameter. For the variant
part, reuse enclosing union even if there is a representation clause
on the Unchecked_Union. If there is a variant part, compute the new
first free position, if any. Adjust call to self. Use a single field
directly only if it hasn't got a representation clause or is placed at
offset zero. Create the variant part at offset 0 if all the fields
down to this level have a rep clause. Do not chain the variant part
immediately and adjust downstream.
Do not test ALL_REP before moving the fields without rep clause to the
previous level. Call create_rep_part to create the REP part and force
a minimum size on it if necessary. Do not chain it immediately.
Create a fake REP part if there are fields without rep clause that need
to be laid out starting from FIRST_FREE_POS.
At the end, chain the REP part and then the variant part.
(create_rep_part): New function.
(get_rep_part): Minor tweak.
* gcc-interface/utils.c (tree_code_for_record_type): Minor tweak.
