rS350540: Only check the blessings table for known LORs.
Summary

Only call it once we've detected a reversal and have set a flag in the
corresponding matrix entries. The badstacks handler now must also omit
stacks corresponding to blessed lock pairs.

Test Plan

Checked that we don't log blessed LORs in badstacks.
