* Support -Wsuggest-override google/benchmark is C++11 compatible but doesn't use the `override` keyword. Projects using google/benchmark with enabled `-Wsuggest-override` and `-Werror` will fail to compile. * Add -Wsuggest-override cxx flag * Revert unrelated formatting * Revert unrelated formatting, take 2 * Revert unrelated formatting, take 3 * Disable -Wsuggest-override when compiling tests, gtest does not handle it yet Co-authored-by: Dominic Hamon <dominichamon@users.noreply.github.com>
