* 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.
