Record edge true/false value for gcov
Make gcov aware which edges are the true/false to more accurately
reconstruct the CFG. There are plenty of bits left in arc_info and it
opens up for richer reporting.
gcc/ChangeLog:
* gcov-io.h (GCOV_ARC_TRUE): New.
(GCOV_ARC_FALSE): New.
* gcov.cc (struct arc_info): Add true_value, false_value.
(read_graph_file): Read true_value, false_value.
* profile.cc (branch_prob): Write GCOV_ARC_TRUE, GCOV_ARC_FALSE.
