Jan, your patch of October 14 had the ChangeLog entries for predict.c
(can_predict_insn_p etc) and toplev.c (rest_of_compilation), but somehow
the actual files failed to get committed. Either commit the files
(preferred) or remove the ChangeLog entry, please. :-)

Incidentally, with only the patch of October 11th (edge cache) the test
case still seems to take forever. We'll see what happens once the patch
of October 14th (eliminating unnecessary queries) is in place; I expect
that to be more important based on your earlier numbers.
