Out-of-memory compiling project that uses fp-ts 0.2.6+ and TS@next

@OliverJAsh kindly provided a small repro:

This fixed the issue for https://github.com/OliverJAsh/ts-2.4-memory-issue, but I ran into another scenario where the memory issue pops up again. I've created a small test case in https://github.com/OliverJAsh/ts-2.4-memory-issue/tree/2.4.0-dev.20170519.

@sledorze additionally noted that the issue happens with ill-typed programs, not well-typed ones.

@sandersn Do you have any tips about how to debug this in a TypeScript application? I'm currently blocked by it :-(

I was able to fix the issue in my example project by deduping fp-ts so there was only one version, not two. The example uses 0.2.8 and 0.2.7. However this was not easy to find, so ideally tsc would tell me the error still.
