Re: [pph] Clean up PPH tests (issue4572042)

After getting new failures due to an unrelated fix, I think this will
be more trouble than it's worth.

First, we can't get rid of the XPASSes, so those will always be noisy.

Second, some XPASSes will need to be unmarked because we just fixed
the underlying problem.

Third, we are at such an early stage, that fixes to a test case will
generally expose failures in other already failing tests, but these
failures will be in a different place.  So more noise.

I really think that for now the easiest way to keep track of this is
to have a clean build to compare against.
