The default behavior of bugpoint is to print "<crash>" when it finds a reduced
test that crashes compilation. With this flag we now can see the output of the
crashing program. This is useful to make sure it is the same error being
tracked down and not a different error that happens to crash the compiler as
well.

In retrospect, it seems "obvious" that the sense of the return code is
the same as if it crashed on "interesting" inputs. But that didn't stop
me from spending more time than I care to admit verifying this.

Late last year r191835 removed a largely unmaintained legacy PGO
infrastructure, but some of the docs were missed. Since these docs are
for things that don't actually exist anymore, they should be removed.
