Bug#734913: gcc-4.9: file conflicts with packages built from src:gcc-4.8

Followup-For: Bug #734913

Hi,

the recent fix did not cover all cases:

* libstdc++-4.9-doc needs to Conflicts: libstdc++-4.8-doc
  (not libstdc++6-4.8-doc)
* libx32stdc++6-4.9-dbg needs to Conflicts: libx32stdc++6-4.8-dbg

To avoid having the list of conflicts growing infinitely in the future,
what about using some virtual packages for the not co-installable
packages, e.g.

Provides: libstdc++-x.y-doc
Replaces: libstdc++-x.y-doc
Conflicts: libstdc++-x.y-doc

(where 'x.y' is a literal string, not something to be substituted)
