We currently only INTEGER_CST, but not POLY_INT_CST, which leads
to the situation that when the POLY_INT_CST is only indrectly
present via a SSA def the IL is valid but when propagated it's not.
That's unsustainable.

Bootstrap and regtest running on x86_64-unknown-linux-gnu, will
push after that succeeded.

        * gimple-expr.cc (is_gimple_mem_ref_addr): Also allow
        POLY_INT_CST.
