936d7218b4 [turbofan] Support lowering of ChangeFloat64ToTagged/ChangeTaggedToInt32.

d9fe1e71c3 [turbofan] Add new ControlEffect and Finish operators. 
Fix the ChangeLowering to properly use ControlEffect nodes
to turn the control output of IfTrue nodes into an effect
input for the Load nodes, and to properly use Finish nodes
to ensure that allocation and store were both performed
prior to actually using the allocated heap number.
