The usual solution of marking the code ineligible for instrumentation forces the code out-of-line, which we would prefer to avoid. Christophe proposed a partial revert, but Nick raised some concerns with that. So for now do a full revert.

Toggle deleted anonymous sets as inactive in the next generation, so users cannot perform any update on it. Clear the generation bitmask in case the transaction is aborted. The following KASAN splat shows a set element deletion for a bound anonymous set that has been already removed in the same transaction.
