[LLVMdev] [RFC] C++11: 'virtual' and 'override'

[Craig Topper]

clang-modernize can add the 'override', but it can't currently delete
'virtual'. It will also potentially overflow 80 columns. And if it removed
virtual it would fail to align a second line of arguments correctly. So you
need modernize and clang-format I guess. Though I'm not sure we want to
widespread apply clang-format.
