sched-deps.c (init_deps): New parameter lazy_reg_last.

2009-11-13  Andrey Belevantsev  <abel@ispras.ru>

        * sched-deps.c (init_deps): New parameter lazy_reg_last.  Don't
        allocate reg_last when in case lazy_reg_last is true.
        (init_deps_reg_last): New.
        (free_deps): When max_reg is 0, this context is already freed.
        * sched-int.h (init_deps_reg_last): Export.
        (init_deps): Update prototype.
        * sched-ebb.c (schedule_ebb): Update the call to init_deps.
        * sched-rgn.c (sched_rgn_compute_dependencies): Likewise.
        * ddg.c (build_intra_loop_deps): Likewise.
        * sel-sched-ir.c (copy_deps_context, create_deps_context,
        reset_deps_context, deps_init_id): Likewise.
        (init_first_time_insn_data): Lazy allocate INSN_DEPS_CONTEXT.
        (free_data_for_scheduled_insn): New, break down from ...
        (free_first_time_insn_data): ... here.
        (has_dependence_p): Allocate reg_last now, when it is needed.
        (extend_insn_data): When maximal LUID is big enough, allocate
        per-insn data in smaller chunks.
        * sel-sched-ir.h (free_data_for_scheduled_insn): Export.
        * sel-sched.c (update_seqnos_and_stage): Free INSN_DEPS_CONTEXT
        in scheduled insn.
