Avoid bogus TwoPhaseState locking sequences
The optimized code in 728bd991c3c4 contains a few invalid locking
sequences. To wit, the original code would try to acquire an lwlock
that it already holds. Avoid this by moving lock acquisitions to
higher-level code, and install appropriate assertions in low-level that
the correct mode is held.
