[vm/compiler] Express control dependence as data dependence. Rationale: This provides a more robust way of expressing control dependences between bounds checks and their uses, while still allowing for CSE and LICM where possible. This also fixes the original bug that started this whole redesign: invalid LICM of checkbound. Note: Deals with bounds check, null check still TBD.
