[PATCH] [analyzer][Review request] Fix for PR18394.

[Антон Ярцев]

  No, the problem remains. There is no node corresponding to CXXDeleteExpr in the CFG.
  The CFG for CXXDeleteExpr before reclaim is
  [DeclRefExpr, PostLValue] -> [DeclRefExpr] -> [ImplicitCastExpr, PostLoad] -> [ImplicitCastExpr] -> [CallEnter]
