As said the most important part is to have user-facing things like
config/powerpcspe/*.opt pruned from irrelevant stuff as well as
a general update for user-facing documentation.  Documentation
updates could be as simple as duplicating any rs6000 specific
documentation and pruning the duplicate from irrelevant parts.
This may need re-surrecting removed doc parts (if there were any)
and/or pruning SPE parts from rs6000 specific documentation
sections.  Esp. install.texi and invoke.texi should be audited
in that respect.

Whether you manage to prune all unreachable code-paths from the 
implementation is not so important for the GCC 8 release.
