Limit how many logical expressions GORI will look back through when evaluating outgoing edge range. PR tree-optimization/100081 * gimple-range-cache.h (ranger_cache): Inherit from gori_compute rather than gori_compute_cache. * gimple-range-gori.cc (is_gimple_logical_p): Move to top of file. (range_def_chain::m_logical_depth): New member. (range_def_chain::range_def_chain): Initialize m_logical_depth. (range_def_chain::get_def_chain): Don't build defchains through more than LOGICAL_LIMIT logical expressions. * params.opt (param_ranger_logical_depth): New.
