gas/hash.c: add new functions
The first of a patch series deleting the gas/hash.c hash table
implementation and instead using libiberty/hashtab.c hash tables in
gas.
* as.h: Include hashtab.h.
* hash.c (htab_insert): New.
(htab_print_statistics): Likewise.
* hash.h (htab_insert): Likewise.
(htab_print_statistics): Likewise.
