* function.h (struct function): New field 'x_naked_return_label'.
* function.c (free_after_compilation): Set it to NULL.
(expand_function_end): Emit 'naked_return_label' if it exists.
* rtl.h (expand_naked_return): Declare.
* stmt.c (expand_naked_return): New function to generate a
jump to 'naked_return_label'.
* builtins.c (expand_builtin_return): Call expand_naked_return
instead of expand_null_return.
* config/sparc/sparc.md (untyped_return): Likewise.
