Libcore's test infrastructure is complicated by the fact that many lang items are defined in the crate. The current approach (realcore/realstd imports) is hacky and hard to work with (tests inside of core::cmp haven't been run for months!). Moving tests to a separate crate does mean that they can only test the public API of libcore, but I don't feel that that is too much of an issue. The only tests that I had to get rid of were some checking the various numeric formatters, but those are also exercised through normal format! calls in other tests.
