[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.

The test is slightly less strict than we'd like because of differences
in type pretty-printing.

(Right now it does show some invalidations - all of those are intentional
and temporary.)
