Updating AUTHORS for companies who have signed CCLA.

Changes:
- Added wildcard rules for company e-mail addresses
- Removed individual e-mail addresses for contributors who are under a corporate
  CLLA (the copyright holder in this case is the company, not the individual
  authors). Domains affected by this change: intel.com, arm.com, codeaurora.org.

In addition, added a wildcard rule for Chromium (which was not previously
listed at all).
