**Is your feature request related to a problem? Please describe.** Currently we can't debug `v8::Value` due to some symbol not exposed After we import `https://github.com/nodejs/node/blob/master/deps/v8/tools/lldb_commands.py` in lldb, if we want to print a v8 value, it's not working  With the result, making hard to debug ```console Failed to evaluate command _v8_internal_Print_Object(*((v8::internal::Object**)((void*)(s).val_))) : error: <user expression 0>:1:44: no member named 'Object' in namespace 'v8::internal' _v8_internal_Print_Object(*((v8::internal::Object**)((void*)(s).val_))) ~~~~~~~~~~~~~~^ error: <user expression 0>:1:52: expected expression _v8_internal_Print_Object(*((v8::internal::Object**)((void*)(s).val_))) ``` This could be fixed by running a debug Node.js, but it's not very friendly for developers.
