[patch, gfortran] PR 22607 again: Return-by-reference functions in modules

When I wrote a patch to fix PR 22607 some time ago
(http://gcc.gnu.org/ml/fortran/2005-11/msg00253.html), I forgot
to check if there were other places where functions were declared
to be "backend-pure", leaving external/module pure
return-by-reference functions still non-working.  This patch
should fix the problem once and for all (I hope).

Reg.tested on Linux/x86, on trunk, 4.1 and 4.0.  Ok to commit?
