* config/tc-m88k.c (get_o6): new function.
(get_bf, get_cmp, get_cnd, get_cr, get_fcr, get_imm16, get_reg,
get_vec9, getval, get_pcr, calcop, match_name): make static and
prototype.
(s_file): remove extraneous forward decl.
(md_begin): add const to retval decl.
(calcop): cope with instructions without arguments. Handle 'o'
type argument, the o6 field of the prot insn.
(md_estimate_size_before_relax): return a dummy value.
