Since swiftlang#64187 we are not importing automatically StringProcessing when building the stdlib -- this is especially important for StdlibUnittest, since it needs to run on older OSes. Addresses rdar://157622116
To do so, use the deployment target versions used for tests. Addresses rdar://157622116

This way they can be used in backdeployment tests.
To do so, use the deployment target versions for tests (not the one for the compiler/stdlib), and remove an unneeded dependency on StringProcessing.
Piggyback a change to disable an Autodiff test on backdeployment configurations
