Make return in memory explicit.
* function.c (aggregate_value_p): Check DECL_BY_REFERENCE.
(assign_parm_find_data_types): Remove code for old front end
invisible reference handling.
(assign_parms): Handle DECL_BY_REFERENCE on the RESULT_DECL.
(expand_function_end): Likewise.
* gimplify.c (gimplify_return_expr): Handle a dereferenced
RESULT_DECL.
* tree-inline.c (copy_body_r): Don't bother looking for &* anymore.
(declare_return_variable): Handle DECL_BY_REFERENCE.
* cp/cp-gimplify.c (is_invisiref_parm): Also handle RESULT_DECL.
(cp_genericize_r): Use convert_from_reference.
Don't dereference a RESULT_DECL directly inside a RETURN_EXPR.
(cp_genericize): Handle the RESULT_DECL. Unset TREE_ADDRESSABLE.
