Comment (by gridaphobe):

 It turns out the patch I attached doesn't actually work for my purposes (I
 think I had only tested it with `-ddump-ticked` instead of building
 LiquidHaskell against it). There's a brief discussion of why on Phab
 (https://phabricator.haskell.org/D1565#inline-13012).

 I can work around this by moving `simpleOptPgm` to a first Core2Core pass,
 thus exposing the fully unoptimized Core to API users and Plugins. But
 that's a much more invasive change, and could break existing API users and
 Plugins.
