3da9072b08 [test] Test changes to accommodate LWG 2904 "Make variant move-assignment more exception safe"
Also: Move constexpr / triviality extension tests into the std tree and make them conditional on _LIBCPP_VERSION / _MSVC_STL_VERSION.

efcf07d44a Remove incorrect #ifdef guards around variant tests.
The tests were previously guarded by #if defined(_LIBCPP_VER) || defined(_MSVC_STL_VER),
which is both incorrect (e.g. _LIBCPP_VERSION) and unneeded. Although the tests are
technically non-standard (yet) they are supported by both libc++ and MSVC's STL.

libstdc++ doesn't regularly use the test suite so I'm not concerned about guarding these
tests for them.

907c1196a7 Add markup for libc++ dylib availability
Libc++ is used as a system library on macOS and iOS (amongst others). In order
for users to be able to compile a binary that is intended to be deployed to an
older version of the platform, clang provides the
availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_
that can be placed on declarations to describe the lifecycle of a symbol in the
library.

See docs/DesignDocs/AvailabilityMarkup.rst for more information.
