[PATCH] Prune references to removed -d{letters} options in invoke.texi (PR middle-end/35853)

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

Honza mailed this patch already in June:
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg01000.html
but hasn't committed it.  I've added a couple of other changes where
non-working -d options were mentioned.

Ok for trunk?
