[turbofan] Initial version of number type feedback. This introduces optimized number operations based on type feedback. Summary of changes: 1. Typed lowering produces SpeculativeNumberAdd/Subtract for JSAdd/Subtract if there is suitable feedback. The speculative nodes are connected to both the effect chain and the control chain and they retain the eager frame state. 2. Simplified lowering now executes in three phases: a. Propagation phase computes truncations by traversing the graph from uses to definitions until checkpoint is reached. It also records type-check decisions for later typing phase, and computes representation. b. The typing phase computes more precise types base on the speculative types (and recomputes representation for affected nodes). c. The lowering phase performs lowering and inserts representation changes and/or checks. 3. Effect-control linearization lowers the checks to machine graphs. Notes: - SimplifiedLowering will be refactored to have handling of each operation one place and with clearer input/output protocol for each sub-phase. I would prefer to do this once we have more operations implemented, and the pattern is clearer. - The check operations (Checked<A>To<B>) should have some flags that would affect the kind of truncations that they can handle. E.g., if we know that a node produces a number, we can omit the oddball check in the CheckedTaggedToFloat64 lowering. - In future, we want the typer to reuse the logic from OperationTyper.

[turbofan] Initial version of number type feedback. This introduces optimized number operations based on type feedback. Summary of changes: 1. Typed lowering produces SpeculativeNumberAdd/Subtract for JSAdd/Subtract if there is suitable feedback. The speculative nodes are connected to both the effect chain and the control chain and they retain the eager frame state. 2. Simplified lowering now executes in three phases: a. Propagation phase computes truncations by traversing the graph from uses to definitions until checkpoint is reached. It also records type-check decisions for later typing phase, and computes representation. b. The typing phase computes more precise types base on the speculative types (and recomputes representation for affected nodes). c. The lowering phase performs lowering and inserts representation changes and/or checks. 3. Effect-control linearization lowers the checks to machine graphs. Notes: - SimplifiedLowering will be refactored to have handling of each operation one place and with clearer input/output protocol for each sub-phase.

[turbofan] Proper dead code elimination as regular reducer. The three different concerns that the ControlReducer used to deal with are now properly separated into a.) DeadCodeElimination, which is a regular AdvancedReducer, that propagates Dead via control edges, b.) CommonOperatorReducer, which does strength reduction on common operators (i.e. Branch, Phi, and friends), and c.) GraphTrimming, which removes dead->live edges from the graph. This will make it possible to run the DeadCodeElimination together with other passes that actually introduce Dead nodes, i.e. typed lowering; and it opens the door for general inlining without two stage fix point iteration. To make the DeadCodeElimination easier and more uniform, we basically reverted the introduction of DeadValue and DeadEffect, and changed the Dead operator to produce control, value and effect. Note however that this is not a requirement, but merely a way to make dead propagation easier and more uniform. We could always go back and decide to have different Dead operators if some other change requires that. Note that there are several additional opportunities for cleanup now, i.e. OSR deconstruction could be a regular reducer now, and we don't need to use TheHole as dead value marker in the GraphReducer. And we can actually run the dead code elimination together with the other passes instead of using separate passes over the graph. We will do this in follow up CLs.
