	* config/tc-mips.c (mips_arg_info): Remove soft_match.
	(match_out_of_range, match_not_constant): New functions.
	(match_const_int): Remove fallback parameter and check for soft_match.
	Use match_not_constant.
	(match_mapped_int_operand, match_addiusp_operand)
	(match_perf_reg_operand, match_save_restore_list_operand)
	(match_mdmx_imm_reg_operand): Update accordingly.  Use
	match_out_of_range and set_insn_error* instead of as_bad.
	(match_int_operand): Likewise.  Use match_not_constant in the
	!allows_nonconst case.
	(match_float_constant): Report invalid float constants.
	(match_insn, match_mips16_insn): Remove soft_match code.  Rely on
	match_float_constant to check for invalid constants.  Fail the
	match if match_const_int or match_float_constant return false.
	(mips_ip): Update accordingly.
	(mips16_ip): Likewise.  Undo null termination of instruction name
	once lookup is complete.
