We really don't know what giants are. They could be trolls, but I would guess they're an earlier idea, one that Tolkien dropped from the lore but not from The Hobbit. It's possible he would have revised it later, like he planned to do in 1960 with the "fairy wife" of the Tooks. However, that edit was never finished, and so we don't know what Tolkien's final intent would be.
