  Fixed 64-bit integer truncation issues in shader translator.
  
  This is an incompatible API change, but one which is necessary in
  order to improve correctness of the code. The API version in
  ShaderLang.h is updated and, unfortunately, the define renamed to
  something less ambiguous due to conflicts on some Android buildbots.
  Temporary patches in Chromium and WebKit will be landed separately to
  support this upgrade.
