Title: Add testcase from pull request #77

It looks like https://github.com/haskell-suite/haskell-src-exts/pull/58 added support for DataKinds, meaning that #77 (which also added support for DataKinds) was unneeded, but 58's test case doesn't cover the various literals while 77's does.

So I cherry-picked it out and here you go.
