re PR rtl-optimization/33737 (verify_flow_info failed: Wrong probability of edge 94->1 -6651)
PR rtl-optimization/33737
* cfgcleanup.c (try_crossjump_to_edge): Add count and frequency of
target block after computing the probabilities of outgoing edges.
Cap the frequency to BB_FREQ_MAX.
* tree-ssa-threadupdate.c (redirect_edges): Also adjust count and
frequency of the basic block if it has been reused.
