Chandler Carruth 7ae684a8b4 Switch statistics to use relaxed updates to a std::atomic. ... This removes usage of the hacky, incorrect, and TSan-unfriendly home-grown atomics. It should actually be more efficient in some cases. Based on our existing usage of <atomic>, all of this is portably available AFAICT. One small challenge is initializing the stastic, but I've tried a comparable sample out on MSVC (the most likely to complain here) and it seems to work. Will have to watch the build bots of course. llvm-svn: 271504		2016-06-02 08:44:05 +00:00
