Log:
[PM] Make default pipeline test for the new PM strict
Use CHECK-NEXT to verify that a test breaks whenever unexpected passes,
analyses, or invalidations show up in default pipelines. The test case
is constructed so that we don't expect to invalidate anything, and needs
to be kept that way.
(Right now it does show some invalidations - all of those are intentional
and temporary.)
