`checkVolatile` overloads

== Synopses

Declared in `<bslmf_invokeresult.h>`

(Declared but not defined) Return `bslmf::Tag<true>()` if the argument is `volatile`‐qualified and `bslmf::Tag<false>()` otherwise. Note that if `t_TP` is both const‐ and volatile‐qualified, it will not match `volatile t_TP&`, hence the need for the const overloads.
