PR tree-optimization/56490
* params.def (PARAM_UNINIT_CONTROL_DEP_ATTEMPTS): New param.
* tree-ssa-uninit.c: Include params.h.
(compute_control_dep_chain): Add num_calls argument, return false
if it exceed PARAM_UNINIT_CONTROL_DEP_ATTEMPTS param, pass
num_calls to recursive call.
(find_predicates): Change dep_chain into normal array,
cur_chain into auto_vec<edge, MAX_CHAIN_LEN + 1>, add num_calls
variable and adjust compute_control_dep_chain caller.
(find_def_preds): Likewise.
