shelley vohr 0e5b6f9300 Upgrade to node v9.3.0 (#11507)
* update submodule refs for node v9.3.0

* Define "llvm_version" for Node.js build

* NODE_MODULE_CONTEXT_AWARE_BUILTIN -> NODE_BUILTIN_MODULE_CONTEXT_AWARE

* update NodePlatform to MultiIsolatePlatform

* fix linting error

* update node ref

* REVIEW: Explicitly register builtin modules

https://github.com/nodejs/node/pull/16565

* update libcc ref

* switch libcc to c62

* REVIEW: Address node api changes

- Always start the inspector agent for https://github.com/nodejs/node/pull/17085
- Set the tracing controller for node https://github.com/nodejs/node/pull/15538
- Isolate data creation now requires plaform https://github.com/nodejs/node/pull/16700
