[PATCH] D15813: [libcxx] Refactoring target_info.py used by lit tests

> This patch makes it easier to support running the lit tests for new and unusual platforms. It will break existing users that set LIBCXX_TARGET_INFO to anything other than the default. I think this is fine, because the old LIBCXX_TARGET_INFO wasn't terribly useful.


I think @danalbert and I are the only users of out-of-tree versions of that.
