S/390: PR79904: Disallow reg + sym_ref literal pool addresses.
We accept reg + sym_ref as valid address if sym_ref is a literal pool
reference knowing that it will be rewritten as r13 + reg + offset.
However, annotate_constant_pool_refs was never able to handle that.
With the patch only single sym_refs are accepted.
Regression tested on s390x.
