What changes were proposed in this pull request?
Update the plan cache after a plan is analyzed.
Why are the changes needed?
The session local plan cache storing unanalyzed logical plans without updating them causes those plans to be repeatedly analyzed, causing performance degradation.
To be specific, a common usage pattern of the session local plan cache (100%) is,
where an unanalyzed plan may be cached during transformation, and Dataset.ofRows analyzes the unanalyzed plan. This leads to a situation where the same query may hit the cache which in turn returns an unanalyzed plan, and Dataset.ofRows again analyzes the same plan.
Does this PR introduce any user-facing change?
