[PATCH] D109609: [C++4OpenCL] Add support for multiple address spaced destructors

[Ronan Keryell via Phabricator via cfe-commits]

keryell added a comment.

While it might be possible to extend arbitrarily C++, I have the feeling that 
having just 1 destructor and have a different code path-code according the 
address space would not be enough.
It is possible to write:

  ~MyDestructor() {
    if constexpr (SomeAPIReturningAddressSpace() == ...::Global) {
      /* Global address space code */
    }
    else if constexpr (...) {
    }
  }

It is possible to build higher-level dispatching constructs from this in OpenCL 
C++ library, for example à la `std::visit` from `std::variant`.
