final.c (cleanup_subreg_operands): Delete some unused code.

	* final.c (cleanup_subreg_operands): Delete some unused code.
	* recog.h (MAX_RECOG_ALTERNATIVES): New macro.
	(struct insn_alternative): New structure definition.
	(recog_op_alt): Declare variable.
	(preprocess_constraints): Declare function.
	* recog.c (recog_op_alt): New variable.
	(extract_insn): Verify number of alternatives is in range.
	(preprocess_constraints): New function.
	* reg-stack.c: Include recog.h.
	(constrain_asm_operands): Delete.
	(get_asm_operand_lengths): Delete.
	(get_asm_operand_n_inputs): New function.
	(record_asm_reg_life): Delete OPERANDS, CONSTRAINTS, N_INPUTS and
	N_OUTPUTS args.  All callers changed.
	Compute number of inputs and outputs here by calling
	get_asm_operand_n_inputs.
	Instead of constrain_asm_operands, call extract_insn,
	constrain_operands and preprocess_constaints.  Use information
	computed by these functions throughout.
	(record_reg_life): Delete code that is unused due to changes in
	record_asm_reg_life.
	(subst_asm_stack_regs): Delete OPERANDS, OPERAND_LOC, CONSTRAINTS,
	N_INPUTS and N_OUTPUTS args.  All callers changed.
	Similar changes as in record_asm_reg_life.
	(subst_stack_regs): Move n_operands declaration into the if statement
	where it's used.
	Delete code that is unused due to changes in subst_asm_stack_regs.
	* stmt.c (expand_asm_operands): Verify number of alternatives is in
	range.
	* Makefile.in (reg-stack.o): Depend on recog.h.
