Maya Lekova 5480e036d2 [megadom] Add TF inlining for Megadom 
The generated code checks if the receiver is a JS_API_OBJECT and if the
receiver requires an access check, and if not it lowers the call to an
API call.

We also add compilation dependencies on the protector cell to deopt if
our invariants change. (Note - the actual invalidation of these cells
will be implemented in a follow up CL)

TOOLS

This directory contains debugging and investigation tools for V8.

The contents are regularly mirrored to http://v8.dev/tools.

Local Development

For local development you have to start a local webserver under http://localhost:8000:

  cd tools/;
  npm install;
  ws;

Local Symbol Server

The system-analyzer can symbolize profiles for local binaries by running a local symbol server

  cd tools/;
  ws --stack system-analyzer/lws-middleware.js lws-static cors;

Note that the local symbol server will run nm and objdump and has access to your files.
