[GHC] #10370: Compile time regression in OpenGLRaw

[Simon Peyton Jones]

Austin: I have validated, but I am now going on holiday for a week.  Can you monitor and revert if there's a major problem?

|  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.
