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.
