  Message : Replace usages of std::vector::data in most cases. In some parts of ANGLE code, we were using std::vector::data to get a pointer to the first element. Sadly, this is c++11 only, which isn't currently supported on Chromium. This was causing a breakage on Android. We should probably refrain from using data except on D3D-only code, which we know will be Visual Studio.
