gas int vs bfd_boolean fixes

	* config/tc-arm.c (struct arm_long_option_table <func>): Return
	bfd_boolean.
	* config/tc-arm.h (arm_optimize_expr, arm_data_in_code): Likewise.
	* config/tc-metag.c (parse_mov_port): Replace unsigned int variable
	with bfd_boolean.
	(parse_mmov, parse_mov_ct, parse_alu, parse_shift, parse_bitop),
	(parse_cmp, parse_fmmov, parse_fmov_data, parse_fearith),
	(parse_dget_set, parse_dalu): Likewise, ensuring assignment from
	logical expressions.
	(struct metag_long_option <func>): Return bfd_boolean.
	(metag_parse_cpu, metag_parse_fpu, metag_parse_dsp): Likewise.
	* config/tc-msp430.c (msp430_dstoperand): Correct dummy type.
	* config/tc-s12z.c (parse_operand_func): Return bfd_boolean.
	(no_operands, lex_force_match, lex_reg_list): Likewise.
	(size_from_suffix): Return int.
	(s12z_relax_frag, md_estimate_size_before_relax): Return 0.
	* config/tc-s12z.h (tc_s12z_fix_adjustable): Likewise.
