  -----------
  [AST] Migrate away from PointerUnion::dyn_cast (NFC) (#124674)

Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:

  // FIXME: Replace the uses of is(), get() and dyn_cast() with
  //        isa<T>, cast<T> and the llvm::dyn_cast<T>

This patch migrates uses of PointerUnion::dyn_cast to
dyn_cast_if_present (see the definition of PointerUnion::dyn_cast).
Note that we already have dyn_cast_if_present<T*>(ExplicitInfo)
elsewhere in ClassTemplateSpecializationDecl and
VarTemplateSpecializationDecl, meaning that ExplicitInfo is not
guaranteed to be nonnull in those classes.
