Comment(by MikolajKonarski):

 Duncan has chosen the last option. The minimal fix on the ghc-events side
 is here:

 [https://github.com/Mikolaj/ghc-
 events/commit/8f20e9f35d73507355f2c90440f5a367a5dcb0bc]

 dcoutts: if you don't mind I'd break the ghc-events API (the utility
 facing part, not the GHC facing part) to keep the order of fiz and gcd
 consistent across all code
 dcoutts: https://github.com/Mikolaj/ghc-
 events/commit/ec4dd1311502f52edce721ea1cefa1becc66706e
 dcoutts: about a dozen changes are required in TS to adapt to the changed
 API
 dcoutts: I think it's better to do the changes now when we remember about
 the fiz and gcd swap
 dcoutts: rather than hunt bugs stemming from the inconsistent order later
 on
