Shu-yu Guo b1020a4345 Reland "[shared-struct] Add Atomics.Condition" 
This is a reland of commit e2066ff6bf

Changes since revert:
- Rebased against c991852491, which
  uses the external pointer table for the WaiterQueueNode stored
  in the state field when compressing pointers. This relaxes
  the alignment requirement of the state field to be 4-bytes when
  compressing pointers.
- Moved the state field into the JSSynchronizationPrimitive base
  class, since alignment and padding can now be made simpler.

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.
