5e4e83e247 Revert "Revert "[cxx-interop] Partially disable a test on Linux"" 
This reverts commit 4cf34abe99.

Unfortunately still failing on Ubuntu 18.04 and Amazon Linux 2.

efc008a2ca [cxx-interop] Import using decls that expose methods from private base classes 
If a C++ type `Derived` inherits from `Base` privately, the public methods from `Base` should not be callable on an instance of `Derived`. However, C++ supports exposing such methods via a using declaration: `using MyPrivateBase::myPublicMethod;`.

MSVC started using this feature for `std::optional` which means Swift doesn't correctly import `var pointee: Pointee` for instantiations of `std::optional` on Windows. This prevents the automatic conformance to `CxxOptional` from being synthesized.

c167f4045b [cxx-interop] Conform std::optional to ExpressibleByNilLiteral 
This will allow passing `nil` as a parameter to a C++ function that takes a `std::optional<T>`.

8f58eafbd3 [cxx-interop] Make sure interop does not trigger TBD validation errors 
This disables TBD validation when C++ interop is enabled, unless an explicit `-validate-tbd-against-ir=` flag was passed.

a12986ade4 [cxx-interop] Add CxxOptional protocol for std::optional ergonomics 
This adds a protocol to the C++ standard library overlay which will improve the ergonomics of `std::optional` when used from Swift code.

As of now, the overlay adds an initializer of `Swift.Optional` that takes an instance of `CxxOptional` as a parameter.
