Sure enough, TO and FROM are not modes. Did mainline just change away from
permissive or something? It surely seems like we ought to have seen this
earlier...
I haven't looked at GET_MODE_XXX, but most, if not of the RTL checking
is disabled because it's too expensive.
I'm hoping that David's work will take us to a place where we can do
more static checking on the RTL bits too.
