Subject: [PATCH] Further work around for clang warnings about typeid() side
 effects.

Apparently in some versions of the compiler even simply dereferencing a
pointer inside typeid() still provokes -Wpotentially-evaluated-expression.
Avoid this by dereferencing it outside and only using typeid() with
references.

Closes #16968.
