Add recursive GORI recompuations with a depth limit.
PR tree-optimization/109154
gcc/
* gimple-range-gori.cc (gori_compute::may_recompute_p): Add depth limit.
* gimple-range-gori.h (may_recompute_p): Add depth param.
* params.opt (ranger-recompute-depth): New param.
gcc/testsuite/
* gcc.dg/Walloca-13.c: Remove bogus warning that is now fixed.
