We currently have a system where the protected instructions are unregistered when the last instance dies, and registered again on the next instantiation. This is triggered by {WasmCompiledModule::Reset}. Since the reference to the {NativeModule} will move to the {WasmModuleObject}, and this object stays alive even if the last instance dies, this will become hard to maintain. It will also make it harder to share wasm code across isolates. This CL refactors this to register trap handler data once when the code is added to the {NativeModule}, and releases it if the code dies.

Don't expose GetFunction on the scope iterator. Simply take it into account for GetFunctionDebugName This is a step towards avoiding materializing function_ altogether if we deoptimize.

The jump optimization maybe run Turbofan pipeline twice for each TF/CS builtins, and relies on the fact that the number of j/jmp instruction generated is always the same. This CL introduces a verification process to ensure that instruction sequence and virtual registers are always the same in two stages, before the final code generation phase.

This CL moves the remaining runtime DataView getters to Torque, namely DataViewGetBigInt64/BigUint64, and removes the associated runtime code that is now unneeded.

For kUpdateEntry and kRemoveEntry, the ArrayBuffer is no longer present on the current page. These are the two most common cases; kKeepEntry is only used for aborted old-page evacuation candidates. Currently we pay the cost of removing the entry from the array_buffers_ map, even though the page itself will be cleared (for new space) or only aborted evacuation candidates will be kept on the page (for old space).
