        * gimple-low.c (struct lower_data): Add the_return_label and
        one_return_stmt.
        (lower_function_body): Initialize and use them.
        (lower_return_expr): New.
        (lower_stmt): Call it.
        * gimplify.c (gimplify_return_expr): Force the argument to be either
        null or a result_decl.
        * tree-gimple.c: Update gimple grammer to match.
        * tree-ssa-copyrename.c (copy_rename_partition_coalesce): Deny
        coalescing of result_decls.

The problem is that return statements no longer have stuff in them any more.
