[PR tree-optimization/68599] Avoid over-zealous optimization with -funsafe-loop-optimizations
PR tree-optimization/68599
* loop-init.c (rtl_loop_init): Set LOOPS_HAVE_RECORDED_EXITS
in call to loop_optimizer_init.
* loop-iv.c (get_simple_loop_desc): Only allow unsafe loop
optimization to drop the assumptions/infinite notations if
the loop has a single exit.
