target-ppc: Implement mulldo with TCG
Optimize mulldo by using the muls2_i64 operation rather than a helper. Eliminate the obsolete helper code. Signed-off-by: Tom Musta <tommusta@gmail.com> Suggested-by: Richard Henderson <rth@twiddle.net> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Alexander Graf <agraf@suse.de>
