Michael Pratt c41bf9ee81 runtime: check partial lock ranking order
To ease readability we typically keep the partial order lists sorted by
rank. This isn't required for correctness, it just makes it (slightly)
easier to read the lists.

Currently we must notice out-of-order entries during code review, which
is an error-prone process.

Add a test to enforce ordering, and fix the errors that have crept in.
Most of the existing errors were misordered lockRankHchan or
lockRankPollDesc.

While we're here, I've moved the correctness check that the partial
ordering satisfies the total ordering from init to a test case. This
will allow us to catch these errors without even running
staticlockranking.
