728b39573c Fix the compilation error for turbofan unsupported platform. 
Fix the compilation error for turbofan unsupported platform. The Linkage::GetOsrValuePosition()
  function is implemented in linkage-impl.h. And this file is included by different platform specific
  file separately. This leads to compilation error for turbofan unsupported platform.

  The fix is adding one dummy implementation in linkage.cc.

925eded364 Saner AUTHORS, part 1: Corporate CLLAs and wildcards. 
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).

aeb09e6dcf Merge v8_optimized_debug 1 and 2 
All builders that used level 1 should meanwhile define
v8_enable_slow_dchecks, and so they can use level 2 without losing
coverage. Level 2, however, is considerably faster, so we want to use it
on those builders as well. The make optdebug setting is not affected by
this change.
