Comment (by simonpj):

 So I did!  I was fixing a whole bunch of things, noted this problem, fixed
 it, and forgot.  Then when building the patch sequence I accidentally
 swept this into the equal-alts patch.

 I think it'll do fine as-is.  Could you add language in `Note [CSE for
 stable unfoldings]` to explain the use of `isAnyInlinePragma`; and point
 to this ticket?  And delete the commented-out `isStableUnfolding`.

 Thanks

 Simon
