[Bug tree-optimization/20165] Pointer does not really escape with write

[tkoenig at gcc dot gnu dot org]

This also causes missed warnings about unitizialized variables:

$ cat foo.f
      print *,x
      end
$ gfortran -O3 -Wall -Wextra foo.f

We should have some way of marking that pointer as read-only.
