  Add a centralized workarounds module.
  
  This is a temporary home for the various workarounds we use
  for performance or to solve driver issues. Eventually we will
  want a standalone library we can use as part of Chromium or
  in ANGLE standalone.
  
  Re-land with member variable initialized.
