We always need to run the profile data phase so that jit stress can inject
random profile counts if it so chooses.

Also, clean up a few dumping nits -- don't dump the profile query status until
we get around to trying to incorporate counts; summarize schema records before
asserting that we must have block counts, etc.

Closes #47839

Two OOMs in x86 jitstress test, seem unrelated (#10002 ?). Will ignore.
