Summary: The only usage there was in GetModificationTime(). I also took the opportunity to move this function from FileSpec to the FileSystem class - since we are using FileSpecs to also represent remote files for which we cannot (easily) retrieve modification time, it makes sense to make the decision to get the modification time more explicit. The new function returns a llvm::sys::TimePoint<>. To aid the transition from TimeValue, I have added a constructor to it which enables implicit conversion from a time_point.
