[turbofan] Introduce CheckHole and CheckHoleNaN operators. These simplified operators are used to perform the hole checks when loading elements from a holey array. Depending on the CheckHoleMode, they either return the hole as undefined or some NaN, or deoptimize if the value is the hole or the hole NaN.
