        Cache that an expression can be moved up only as RHS.

        * sel-sched.c (enum MOVEUP_RHS_CODE): New value MOVEUP_RHS_AS_RHS.
        (moveup_rhs): Return it when an expression can be moved up as
        a RHS only.  Return MOVEUP_RHS_CHANGED only when expression
        was really changed.
        (moveup_set_rhs): Use fourth bit in INSN_ANALYZED_DEPS /
        INSN_FOUND_DEPS bitmaps for caching MOVEUP_RHS_AS_RHS results.
        Set EXPR_TARGET_AVAILABLE to false when moveup_rhs returns
        MOVEUP_RHS_AS_RHS.  Assert that when MOVEUP_RHS_CHANGED,
        expression's UID has been really changed.
        (fill_vec_av_set): Properly handle max_insns_to_rename.
        (sel_global_init): Use setup_sched_dumps.

        * sel-sched-dump.c (setup_sched_dump_to_stderr): Rename to
        setup_sched_dumps.  When sched_verbose_param >= 10, print to
        stderr.
        * sel-sched-dump.h (setup_sched_dumps): Export.
