With revision 139538 these tests passed.

I'm including ipa-7 too, as it was changed in this revision range (it worked
with revision 139521 and has failed since revision 139525) but the message was
originally

Running /tmp/hpautotest-gcc1/gcc/gcc/testsuite/gcc.dg/ipa/ipa.exp ...
FAIL: gcc.dg/ipa/ipa-7.c scan-ipa-dump-times cp "propagating const" 1

I also included the ipacost messages above as they have never passed, but
I'll open a separate PR if requested.  No further clues in gcc.log.

>From <http://gcc.gnu.org/ml/gcc-regression/2008-08/msg00096.html> it looks like
this fails on many more targets, and that it was a narrower revision range:
pass 139540 to fail 139545.
