	(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.

	where it's used.
	Delete code that is unused due to changes in subst_asm_stack_regs.

        * gthr-vxworks.h (__ehdtor): Fix memory leak.  The delete hook
        runs in the context of the deleter, not the deletee, so we must
        use taskVarGet to find the correct memory to free.
        (__gthread_key_create): Initialize the task
        variable subsystem so that the task variable is still active when
        the delete hook is run.
