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.
