Comment (by simonpj):

 The commit messages tell the story.  Reid's example in comment:3 showed up
 TWO separate, substantial non-linear performance holes in GHC, both of
 which I have now fixed.  Reid, your example was amazingly helpful.

 '''Austin''' I have not added a `perf/compiler` test case.  Could you do
 so please?  I wasn't sure that a 20-second compile time was acceptable.
 I'm leaving the ticket open for that reason.

 Simon
