Another case of duplicated hash.h code, the only minor difference being that macro->format_hash was created with 7 entries vs. str_hash with 16 entries. * macro.c (macro_init, define_macro): Use str_htab_create. (do_formals, define_macro, macro_expand_body): Use str_hash_insert (macro_expand_body): Use str_hash_find and str_hash_delete. (delete_macro): Likewise. (sub_actual, macro_expand, check_macro): Use str_hash_find. (expand_irp): Use str_htab_create and str_hash_insert. * macro.h (struct macro_struct): Tidy. (struct macro_hash_entry, macro_hash_entry_t, hash_macro_entry), (eq_macro_entry, macro_entry_alloc, macro_entry_find), (struct formal_hash_entry, formal_hash_entry_t), (hash_formal_entry, eq_formal_entry, formal_entry_alloc), (formal_entry_find): Delete. * config/tc-iq2000.c (iq2000_add_macro): Use str_htab_create and str_hash_insert.
