Since we're not yet sure of the design of Experimental/UseExperimental, we're making them "experimental" themselves in some sense, in that the user is required to provide the magic argument "-Xuse-experimental=kotlin.Experimental" to be allowed to use either Experimental or UseExperimental. This is more convenient than the previous approach of "-language-version 1.3 -Xskip-metadata-version-check" because it's simpler and does not cause pre-release binaries to be produced
