tree-optimization/100081 - Limit depth of logical expression windback.
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.
