In a recent CL (https://crrev.com/c/1012039) I removed the only valid use case of {external_reference_redirector}. In this CL I remove the remaining uses, which are more or less checks if there is a simulator or not.

With this CL we do the redirection of ExternalReferences for simulators independent of the isolate but instead use the redirector provided by the simulator directly. Thereby we make the code independent of the isolate. I plan to remove the redirector from the isolate in a separate CL.

This adds another fixed spill slot to the {WasmCompiledFrame} layout, holding a reference to the current {WasmInstanceObject}. This slot allows the stack walker to retrieve instances for WebAssembly frames without having each code object be coupled to an instance. Hence it enables sharing code across instances in the future.

The Cvtui2ss method did overwrite the {src} register, and the given {tmp} register. Because of this, the Turbofan code generator passed two temporary registers.

Previously Isolate and Factory relied on the undefined behavior of reinterpret_cast to switch between the two unrelated classes (which worked because Factory had no data members). With Isolate inheriting from Factory, it's now possible to switch between the two classes using c-style casts. These are allowed under the C++ standard. The inheritance is private which allows the continuing separation of the Factory and Isolate namespaces. This is a defensive clean-up, since ubsan does not yet detect the previous undefined behavior.
