Similarly to the patch for cmpstr(n), this patch uses the optabs
interface for cmpmem instead of using HAVE_cmpmmsi and CODE_FOR_cmpmemsi
directly.

Tested on x86_64-linux-gnu.  OK to install?

Thanks,

gcc/
        * builtins.c (expand_cmpstrn): Rename to...
        (expand_cmpstrn_or_cmpmem): ...this.
        (expand_builtin_strcmp, expand_builtin_strncmp): Update accordingly.
        (expand_builtin_memcmp): Use optabs instead of HAVE_cmpmem/gen_cmpmem.
        Remove mode argument.
        (expand_builtin): Update accordingly.

OK.
