Used to annotate `unittest`s which need to be tested in a `-betterC` environment.

Such `unittest`s will be compiled and executed without linking druntime in, with
a `__traits(getUnitTests, mixin(__MODULE__))` style test runner.
Note that just like any other `unittest` in phobos, they will also be compiled
and executed without `-betterC`.
