For whoever is concerned about memory usage, I didn't measure a real
increase, besides a few KB. These are very hot allocation pools and
allocating too many blocks of 10 elements is suboptimal.

* cselib.c (cselib_init): Increased initial size of elt_list_pool,
elt_loc_list_pool, cselib_val_pool, value_pool allocation pools
since they are very frequently used.
