re PR rtl-optimization/83030 (ICE in create_pseudo_cfg, at dwarf2cfi.c:2840)
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.
