[Bug tree-optimization/104676] [12 Regression] ICE in verify_loop_structure, at cfgloop.cc:1748 (error: loop 3's number of iterations '(unsigned int) + 4294967295' references the released SSA name '<unknown>')

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
loop distribution removes

_31 = s_18(D)->f;

releasing SSA name 31 but loop 3 still has nb_iterations == (unsigned int) _31
+ 4294967295

loop distribution already does scev_reset_htab but should just use scev_reset
here.
