Add JEMALLOC_COLD, and mark some functions cold.
...
This hints to the compiler that it should care more about space than CPU (among
other things). In cases where the compiler lacks profile-guided information,
this can be a substantial space savings.
For now, we mark the mallctl or atexit driven profiling and stats functions that
take up the most space.

prof_recent: cassert(config_prof) more often.
...
This tells the compiler that these functions are never called, which lets them
be optimized away in builds where profiling is disabled.
