While we've found and fixed many gopls crashes thanks to telemetry, as we gain more users it appears we're accumulating a long tail of issues that "can't happen" based on easily verifiable local invariants.

In some cases, these were related to misreporting of stacks by the runtime (#70637), but others cannot be explained by a misreported stack, and indicate some form of memory corruption or (most likely) data race.

This issue is an umbrella for those bugs. @adonovan and I will consolidate them here.
