Iron golems should be able to reach players on a 3-block pillar

This would force players to use a spear to destroy this mob, as it adds attack range, and the golem would no longer be able to reach a player on a 4-block pillar. In theory, an iron golem's attack range (2 tiles) should already be enough to reach a player on a 3-block pillar. The problem may be that this attack range is measured not from hand height (just under 2 blocks), but below. The advantages of this solution are: 1) Makes the fight with the golem more interesting and logical. 2) Gives a new use for the spear.
