Minor fix

1. Changes in config.hpp

   • Missing compile setting in config.hpp leads to confusing warning when binding cores.

2. Changes in loader/base_loader.hpp

   • Add loading check before minus one since "gstore->num_normal_preds == -1" will lead to endless loop in function [init_seg_metas].

3. Changes in mm/jemalloc.hpp, store/dynamic_gstore.hpp

   • jemalloc.hpp: add range check to notify the reason why "memory range false" happened. This is just to make debugging easier.
   • dynamic_gstore.hpp: fix bug when insert idx.
