Later patches allow using SVE modes in ldp/stp with -msve-vector-bits=128,
so we need to make sure that we don't use SVE addressing modes when
printing the address for the ldp/stp.

This patch does that.

Bootstrapped/regtested as a series on aarch64-linux-gnu, OK for trunk?

gcc/ChangeLog:

        * config/aarch64/aarch64.cc (aarch64_print_address_internal): Handle SVE
        modes when printing ldp/stp addresses.
