Add README files explaining the differentiable programming test suite. Add lit.local.cfg files so individual tests do not need to add `REQUIRES: asserts` in these directories: - test/AutoDiff/compiler_crashers - test/AutoDiff/compiler_crashers_fixed Motivation: it is important for compiler crasher tests to require assertions enabled, because many of these tests crash on compiler assertions.
