Comment (by simonpj):

 Interesting.   Thanks for reducing the test case.  No time to look at it
 now, but can you characterise what is happening more.   E.g. what happens
 with `-dshow-passes`?  Does the program get really big at some point?
 What's the difference between 7.8 and 7.10.  Is it non-linear somehow?
 etc.
