* The size2index_tab lookup table uses uint8_t to encode each bin index, so we
* cannot support more than 256 small size classes. Further constrain NBINS to
* 255 since all small size classes, plus a "not small" size class must be
* stored in 8 bits of arena_chunk_map_bits_t's bits field.
* cannot support more than 256 small size classes.
