Comment (by dalaing):

 I've been having a go at this, and I'm up to the code gen part.

 It looks like there's a decent amount of the Cmm code that takes a
 `DynFlags` argument in order to get access to `PlatformConstants`.

 The `PprFlags` change might be easier if these functions took
 `PlatformConstants` as an argument (which would then become part of the
 `PprFlags` structure).

 Does anyone have thoughts on whether I should just go ahead and do this?
 Or should I make `CmmFlags` and `cmmFlags :: DynFlags -> CmmFlags` in
 order to wrap it nicely?
