It sounds to me like the best thing might be to have:

  #define SET_CP_DECL_CONTEXT(NODE, CONTEXT) \
    (DECL_CONTEXT (NODE) = FROB_CONTEXT (NODE, CONTEXT))

and use that everywhere.  I'd rather not be clever about where we might
have to use it and where we might not.

(IMO, the ideal representation would have global_namespace for
DECL_CONTEXT -- but that's not a change we can make without affecting
the middle end, as you've noticed, so I think having
{SET_,}CP_DECL_CONTEXT to insulate us would be a nice improvement.
