Remove the template magic from types.(h|cc), remove types-inl.h. This CL removes the Config templatization from the types. It is not necessary anymore, after the HeapTypes have been removed. The CL also changes the type hierarchy - the specific type kinds are not inner classes of the Type class and they do not inherit from Type. This is partly because it seems impossible to make this work without templates. Instead, a new TypeBase class is introduced and all the structural (i.e., non-bitset) types inherit from it. The bitset type still requires the bit-munging hack and some nasty reinterpret-casts to pretend bitsets are of type Type*. Additionally, there is now the same hack for TypeBase - all pointers to the sub-types of TypeBase are reinterpret-casted to Type*. This is to keep the type constructors in inline method definitions (although it is unclear how much that actually buys us). In future, we would like to move to a model where we encapsulate Type* into a class (or possibly use Type where we used to use Type*). This would loosen the coupling between bitset size and pointer size, and eventually we would be able to have more bits.

[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.

[TurboProp] Remove unreachable successor basic blocks from schedule. Effect-control-linearizer will update a basic block to connect it directly to the end node if it has an Unreachable node. Usually the block would already have been connected directly to end (via a Throw node) already, however in some cases it can be connected indirectly (via a branch, where both end in a throw node). If this happens, and the Effect-control-linearizer is maintaining the schedule (e.g., for TurboProp), it will cause the end block to have unreachable predecessor blocks, which can cause issues with the register allocator. To fix this, have the BasicBlockUpdater remove all successor blocks from the schedule, when they become Unreachable. Also add some tests to cover this in effect-control-linearizer-unittests.

[turbofan] Introduce node regions for protection from scheduling. This CL re-purposes ValueEffect and Finish as delimiters for regions that are scheduled atomically (renamed to BeginRegion, FinishRegion). The BeginRegion node takes and produces an effect. For the uses that do not care about the placement in the effect chain, it is ok to feed graph->start() as an effect input. The FinishRegion takes a value and an effect and produces a value and an effect. It is important that any value or effect produced inside the region is not used outside the region. The FinishRegion node is the only way to smuggle an effect and a value out. At the moment, this does not support control flow inside the region. Control flow would be hard. During scheduling we do some sanity check, but the checks are not exhaustive. Here is what we check: - the effect chain between begin and finish is linear (no splitting, single effect input and output). - any value produced is consumed by the FinishRegion node. - no control flow outputs.

[turbofan] Introduce an ExternalPointer type. This adds a new ExternalPointer type, which is an Internal type that is used for ExternalReferences and other pointer values, like the pointers into the asm.js heap. It also adds a PointerConstant operator, which we use to represents these raw constants (we can probably remove that particular operator again once WebAssembly ships with the validator).

[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.

SIMPLIFIED_SPECULATIVE_NUMBER_BINOP_LIST(DECLARE_SPECULATIVE_BINOP_MATCHER)
[turbofan] Eliminate redundant Smi checks around array accesses. As identified in the web-tooling-benchmark, there are specific code patterns involving array indexed property accesses and subsequent comparisons of those indices that lead to repeated Smi checks in the optimized code, which in turn leads to high register pressure and generally bad register allocation. An example of this pattern is code like this: ```js function f(a, n) { const i = a[n]; if (n >= 1) return i; } ``` The `a[n]` property access introduces a CheckBounds on `n`, which later lowers to a `CheckedTaggedToInt32[dont-check-minus-zero]`, however the `n >= 1` comparison has collected `SignedSmall` feedback and so it introduces a `CheckedTaggedToTaggedSigned` operation. This second Smi check is redundant and cannot easily be combined with the earlier tagged->int32 conversion, since that also deals with heap numbers and even truncates -0 to 0. So we teach the RedundancyElimination to look at the inputs of these speculative number comparisons and if there's a leading bounds check on either of these inputs, we change the input to the result of the bounds check. This avoids the redundant Smi checks later and generally allows the SimplifiedLowering to do a significantly better job on the number comparisons. We only do this in case of SignedSmall feedback and only for inputs that are not already known to be in UnsignedSmall range, to avoid doing too many (unnecessary) expensive lookups during RedundancyElimination. All of this is safe despite the fact that CheckBounds truncates -0 to 0, since the regular number comparisons in JavaScript identify 0 and -0 (unlike Object.is()). This also adds appropriate tests, especially for the interesting cases where -0 is used only after the code was optimized.

[turbofan] Right hand side of shifts needs ToUint32. Currently we lower shifts directly to machine operators, and add an appropriate Word32And to implement the & 0x1F operation on the right hand side required by the specification. However for Word32And we assume Int32 in simplified lowering, which is basically changes the right hand side bit interpretation for the shifts from Uint32 to Int32, which is obviously wrong. So now we represent that explicitly by proper simplified operators for the shifts, which are lowered to machine in simplified lowering.

[turbofan] Introduce a pure StringConcat operator. This replaces the previous CheckStringAdd operator which deopts in case the combined length overflows with a dedicated pure StringConcat operator. This operator is similar to NewConsString in that it takes the resulting length plus the two input strings. The operator relies on the length being checked explicitly by the surrounding code instead of baking the check into the operator itself. This way TurboFan can eliminate redundant/unnecessary StringConcat operations, since they are pure now. This also unifies the treatment of string addition in JSTypedLowering, and generalizes the StringLength constant-folding to apply to more cases not just the JSAdd cases inside JSTypedLowering.

[turbofan] Introduce a dedicated StringLength operator. Strings are immutable in JavaScript land (contrast with the runtime, where we can truncate strings that haven't escaped to JavaScript yet), so the length of a String is immutable. Thus loading the length of a String is a pure operation and should be expressed as such (i.e. doesn't depend on control or effect). The StringLength operator does exactly this and is hooked up to the effect chain in the EffectControlLinearizer. This will eventually allow us to simplify the optimization of string concatention and other operations that are a bit cumbersome in TurboFan currently, and it will also allow us to optimize string operations across effectful operations, for example combining multiple invocations to String#slice with the same inputs.

Because the returned value cannot change through the execution of a function, LoadImmutable is a pure operator and does not have effect or control edges. This will allow more aggressive optimizations of loads of fields of the Isolate and Instance that are known to be immutable. Requires that the memory in question has been initialized at function start even through inlining. Note: We may reconsider this approach once we have escape analysis for wasm, and replace it with immutable load/initialize operators that live inside the effect chain and are less restriced.

[turbofan] Introduce TruncateTaggedToWord32 simplified operator. This allows us to get rid of the "push TruncateFloat64ToInt32 into Phi" trick that was used in the MachineOperatorReducer to combine the ChangeTaggedToFloat64 and TruncateFloat64ToInt32 operations. Instead of doing that later, we can just introduce the proper operator during the representation selection directly. Also separate the TruncateFloat64ToInt32 machine operator, which had two different meanings depending on a flag (either JavaScript truncation or C++ style round to zero). Now there's a TruncateFloat64ToWord32 which represents the JavaScript truncation (implemented via TruncateDoubleToI macro + code stub) and the RoundFloat64ToInt32, which implements the C++ round towards zero operation (in the same style as the other WebAssembly driven Round* machine operators).

Once this solution is stabilized, we can use it for Math.floor as well. And once that is settled, we can establish it as the unified way to inline builtins, and get rid of the specialized builtin function id based inlining at some point. Note that "builtin" applies to basically every piece of internal JavaScript/intrinsics based code, so this also applies to the yet to be defined JavaScript based code stubs and handlers.

[turbofan] Introduce dedicated NumberToBoolean operator.

However this doesn't always generate the best, especially when we can later derive from feedback that x is always an Integral32 value, where the ideal code would be just a single comparison to 0 w/o the absolute value computation.

[interpreter] Add basic framework for bytecode handler code generation. Adds basic support for generation of interpreter bytecode handler code snippets. The InterpreterAssembler class exposes a set of low level, interpreter specific operations which can be used to build a Turbofan graph.

[turbofan] Introduce PlainPrimitiveToNumber. This should solve the problem with missing checkpoints after JSToNumber (PlainPrimitiveToNumber is marked no-write, so the frame-state propagation should see through it.)
