IPA PTA stats enhancement and non-details dump slimming
The following keeps track of the number of edges we avoid to create
because they redundandly feed ESCAPED. It also avoids printing
a header for -details when not using -details.
* tree-ssa-structalias.cc (constraint_stats::num_avoided_edges):
New.
(add_graph_edge): Count redundant edges we avoid to create.
(dump_sa_stats): Dump them.
(ipa_pta_execute): Do not dump generating constraints when
we are not dumping them.
