Enable new warning for fragile/incorrect CPP #if usage
The C code in the RTS now gets built with `-Wundef` and the Haskell code (stages 1 and 2 only) with `-Wcpp-undef`. We now get warnings whereever `#if` is used on undefined identifiers. Test Plan: Validate on Linux and Windows Reviewers: austin, angerman, simonmar, bgamari, Phyx Reviewed By: bgamari Subscribers: thomie, snowleopard Differential Revision: https://phabricator.haskell.org/D3278
