  Message : bench: Modify benchmarks for a wider range of platforms - Add the new files bench.c and bench.h to implement a timer module. - Implement the module with clock_gettime(), mach_absolute_time(), or gettimeofday(), depending on a given platform. - Replace the time measurement code of the benchmark programs with the functions of the module.
