* add fuzzers for chrono timepoint and localtime,gmtime * reorder cases to improve throughput mutating the first byte of the input now always results in picking on of the two paths. Before, two of the four possible outcomes resulted in doit() not being invoked. * drop the localtime fuzzer * inline aliases * only fuzz std::chrono::system_clock
