This flag was not experimental for any good reason; it should always be enabled. The flag only exists so we can introduce a new API: UnsafeMutablePointer.mutableSpan. Supported compilers cannot handle the new API. rdar://154247502 (Promote feature NonescapableAccessorOnTrivial to be non-experimental) (cherry picked from commit 3dc0e622bac5576bdb29ab343b46f6492dd4b9ff)
