Log:
        PR rtl-optimization/83030
        * doc/rtl.texi (Flags in an RTL Expression): Alphabetize, add entry
        for CROSSING_JUMP_P and mention usage of 'jump' for JUMP_INSNs.
        (Insns): Delete entry for REG_CROSSING_JUMP in register notes.
        * bb-reorder.c (update_crossing_jump_flags): Do not test whether the
        CROSSING_JUMP_P flag is already set before setting it.
        * cfgrtl.c (fixup_partition_crossing): Likewise.
        * reorg.c (relax_delay_slots): Do not consider a CROSSING_JUMP_P insn
        as useless.
