Hi all,

In GCC 9 the aarch64 port learned how to do V16QImode SAD operations on signed and unsigned chars.
But I had missed enabling the effective target for that.
This patch enables that target for non-SVE aarch64.
Two new tests now PASS on aarch64:

Ok for trunk?


P.S. I notice that powerpc and mips also implement the necessary optabs.
Perhaps the maintainers would like to check that the tests above pass on their appropriate (sub)targets and
enable this effective target appropriately.

     * lib/target-supports.exp (check_effective_target_vect_usad_char):
     Add non-SVE aarch64 to supported list.
