Actually, i checked the game.. he doesn't do those.
N64: "fixes Tunic" "swings sword" "looks around" "shakes his shield" "clamps his boots" "yawns and stretches"
3DS: all of the above mentioned plus "shivers" "sneezes" "acts as if he's hot"

So, the new animations i've seen so far are:
~Link's running animation is smoother
~Link has the Sword Twirl first seen in Twilight Princess when targeting
~In hot/humid...
