TestReplaceNarrowPhiWithBottomPhi fails on ppc64 platforms when running fastdebug binaries.
Example output is from AIX, but the test fails too on Linuxppc64le .

One or more @IR rules failed:

   - To only run the failed tests use -DTest, -DExclude,
     and/or -DScenarios.
   - To also get the standard output of the test VM run with
     -DReportStdout=true or for even more fine-grained logging
     use -DVerbose=true.
