Comment (by rwbarton):

 Simon, it looks like you implemented the first bullet point in your
 comment above in 55efc9718b520ef354e32c15c4b49cdfecce412f "Combine
 identical case alternatives in CSE", though the old version is commented
 out.
 {{{#!diff
 +noCSE :: InId -> Bool
 +noCSE id = not (isAlwaysActive (idInlineActivation id))
 +             -- See Note [CSE for INLINE and NOINLINE]
 +         || isAnyInlinePragma (idInlinePragma id)
 +             --isStableUnfolding (idUnfolding id)
 +             -- See Note [CSE for stable unfoldings]
 +         || isJoinId id
 +             -- See Note [CSE for join points?]
 }}}
 Did you mean to commit this in this form? It did fix the test associated
 to this ticket.
