         * config/i386/i386.c (ix86_dep_by_shift_count_body) : Add
         check on reload_completed since it can be invoked before
         register allocation phase in pre-reload schedule.
         (ia32_multipass_dfa_lookahead) : Do not use dfa_lookahead for pre-reload
         schedule to save compile time.
         (ix86_sched_reorder) : Do not perform ready list reordering for pre-reload
         schedule to save compile time.
         (insn_is_function_arg) : New function. Returns true if lhs of insn is
         HW function argument register.
         (add_parameter_dependencies) : New function. Add output dependencies
         for chain of function adjacent arguments if only there is a move to
         likely spilled HW registers. Return first argument if at least one
         dependence was added or NULL otherwise.
         (avoid_func_arg_motion) : New function. Add output or anti dependency
         from insn to first_arg to restrict code motion.
         (add_dependee_for_func_arg) : New function. Avoid cross block motion of
         function argument through adding dependency from the first non-jump
         insn in bb.
         (ix86_dependencies_evaluation_hook) : New function. Hook for pre-reload schedule:
         avoid motion of function arguments passed in passed in likely spilled
         HW registers.
         (ix86_adjust_priority) : New function. Hook for pre-reload schedule: set priority
         of moves from likely spilled HW registers to maximum to schedule them
         as soon as possible.
         (ix86_sched_init_global): Do not perform multipass scheduling for pre-reload
         schedule to save compile time.
