Remove MAX_SWITCH_CASES limit
The following removes the MAX_SWITCH_CASES limit to fight quadraticness
when looking up case labels from edges. Instead use the
{start,end}_recording_case_labels facility for that. For it to be
usable I've exported get_cases_for_edge from tree-cfg.cc.
* tree-cfg.h (get_cases_for_edge): Declare.
* tree-cfg.cc (get_cases_for_edge): Export.
* tree-ssa-uninit.cc (execute_late_warn_uninitialized):
Start and end recording case labels.
* gimple-predicate-analysis.cc (MAX_SWITCH_CASES): Remove.
(predicate::init_from_control_deps): Use get_cases_for_edge.
