Will napi_set_function_name work with spidermonkey #26

• Version: ALL
• Platform: ALL
• Subsystem: API

Comment from Ben in nodejs/node-eps#20 (comment), we'll need to see if:

NODE_EXTERN void napi_set_function_name(napi_env e, napi_value func,
+                                        napi_propertyname napi_value);

will work with other engines like spidermonkey were the name it declared up front.
