Summary: The main motivation for this is unit tests, which contain a large macro for pretty-printing std::error_code, and this macro is duplicated in every file that needs to do this. However, the functionality may be useful elsewhere too. In this patch I have reimplemented the existing ASSERT_NO_ERROR macros to reuse the new functionality, but I have kept the macro (as a one-liner) as it is slightly more readable than ASSERT_EQ(..., std::error_code()).
