Add parserTests blacklist.

We now compare failing tests with a list of those "expected to fail".
You can easily update the blacklist with ./parserTests --rewrite-blacklist

"./parserTests --quiet" now doesn't generate any output for expected
passes or expected failures, showing only the tests which have changed.
