Comment (by dalaing):

 Here's the stuff currently being used in SDoc computations, pulled out
 into 'PprFlags':

 {{{

 data PprFlags = PprFlags {
     pprCols          :: Int
   , pprUserLength    :: Int

 There might be a few more - I was nearly done when this conversation
 started, and figured I should pause until it was clear that something like
 this was wanted.

 Most of the signature changes are in the CmmCode, where there are loads of
 functions that currently take 'DynFlags' which I changed to take
 'PlatformConstants', since there are large chunks of code that only need
 the 'DynFlags' in order to access 'PlatformConstants', and these functions
 get used in the pretty printer / codegen intersection.
