When COMPRESS_STAT is not set, and RED_WORKER_STAT is set, stat_time() will be a no-op, but stat_start_time_init() will try to use stat_info_t::clock. This causes a compile warning on 32 bit arches (not sure why not on 64 bit builds), as well as an error from valgrind. Since stat_time() and stat_compress_time() are both doing the same work, this commit makes them the same function, which ensures stat_info_t::clock will be set and stat_start_time_init() can be used regardless of the _init() method which is called.
