Improve uninit_analysis::collect_phi_def_edges
This avoids expanding an edge to those of a PHI def if it is not
may-undefined, reducing the number of compute_control_dep_chain calls.
* gimple-predicate-analysis.cc
(uninit_analysis::collect_phi_def_edges): Only expand a
PHI def edge when it is possibly undefined.
