tree-optimization/110298 - CFG cleanup and stale nb_iterations
When unrolling we eventually kill nb_iterations info since it may
refer to removed SSA names. But we do this only after cleaning
up the CFG which in turn can end up accessing it. Fixed by
swapping the two.
PR tree-optimization/110298
* tree-ssa-loop-ivcanon.cc (tree_unroll_loops_completely):
Clear number of iterations info before cleaning up the CFG.
* gcc.dg/torture/pr110298.c: New testcase.
