Tobias Tebbi ac0661b358 Reland^5 "[turbofan] eagerly prune None types and deadness from the graph" 
This gives up on earlier attempts to interpret DeadValue as a signal of 
unreachable code. This does not work because free-floating dead value 
nodes, and even pure branch nodes that use them, can get scheduled so
early that they get reachable. Instead, we now eagerly remove branches
that use DeadValue in DeadCodeElimination and replace DeadValue inputs 
to value phi nodes with dummy values.
