PR rtl-optimization/38449:
* hooks.c (hook_bool_const_rtx_const_rtx_true): New function.
* hooks.h (hook_bool_const_rtx_const_rtx_true): Declare.
* target.def: Merge in definitions and documentation for
TARGET_CAN_FOLLOW_JUMP.
* doc/tm.texi.in: Add documentation locations for the above.
* doc/tm.texi: Regenerate.
* reorg.c (follow_jumps): New parameters jump and crossing.
Changed all callers.
