Michael Zolotukhin 09b5b54897 ProvenanceAnalysis: Store WeakTrackingVH instead of Value* in UnderlyingValue Cache.
Summary:
Since the value stored in the cache might be deleted or replaced with
something else, we need to use tracking ValueHandlers instead of plain
Value pointers. It was discovered in one of internal builds, and
unfortunately there is no small reproducer for the issue.

The cache was introduced in rL327328.
