Reid Kleckner 19ff5602da Thread Safety Analysis: Fix DenseMap iterator invalidation UAF ...

Rather than storing BeforeInfo in the DenseMap by value, this stores a
unique_ptr to it, so that we can keep a pointer to it live across
subsequent DenseMap insertions.

This change also removes the unique_ptr wrapper around BeforeVect
because now we're indirecting at a higher level.
