Improve uninit pass dumping
This produces less redundancy and more complete info dumping
the control dependence chains.
* gimple-predicate-analysis.cc (format_edge_vec): Dump
both source and destination.
(dump_dep_chains): Remove.
(uninit_analysis::init_use_preds): Remove redundant
dumping of chains.
