This CL extracts the capturing for detailed and simple stack traces into a configurable helper. Rather then introducing a single flag for this helper, noting whether we capture simple or detailed stack traces, each "difference" between the two can be turned on/off separately, for easier, future refactorings.

This updates the existing special casing of assignment operators by gcmole to match for assignments of {HeapObject} instead of {HeapObject*} variables. The former now uses the implicit C++ assignment operator call instead of a primitive assignment binary operation. Also removes the dead {handle_decl_name} field as a drive-by-fix.

This CL just adds a parameter to addElementSegment and adjusts all existing tests. Note that addElementSegment contains some convenience code to construct one initial table if it does not exist yet. I did not extend that code to multiple tables. If you want to use multiple tables, you have to create them first before calling addElementSegment.

We need to ensure that the NativeModule stays alive while any {BackgroundCompileScope} exists, because during that time we hold shared ownership of the mutex in the {BackgroundCompileToken}. If the {NativeModule} dies during that period, we would need to get exclusive ownership of the mutex and deadlock. This change requires holding a {std::weak_ptr<NativeModule>} in the BackgroundCompileToken instead of a raw pointer, hence it can only be initialized after the NativeModule was created. This is done via a separate {InitCompilationState} method.

The TryGetOwnProperty code supports only unique names that are not array indices. Unfortunately, this is neither obvious from its type, nor from its comment, nor from its code. ProxiesCodeStubAssembler::CheckHasTrapResult violated the assumption and was already fixed a few days ago. This CL fixes CheckGetSetTrapResult and improves our code documentation in the form of comments and assertions. Concretely: - Add CodeStubAssembler::IsUniqueName and IsUniqueNameNoIndex - Use IsUniqueNameNoIndex in CheckGetSetTrapResult to guard TryGetOwnProperty (bailout to runtime if not satisfied). - Similarly, use IsUniqueNameNoIndex to simplify the previous fix in CheckHasTrapResult. - Add a IsUniqueNameNoIndex CSA_ASSERT to TryGetOwnProperty and a few other places to avoid such bugs in the future. - Add a IsUniqueName CSA_ASSERT to a few places where we apparently expect unique names (I don't know if those allow indices or not). - Add a DCHECK to Name::IsUniqueName to ensure and document that this shortcut version is equivalent to HeapObject::IsUniqueName.

In particular, remove {toUint8Array} method and make {toBuffer} return a {Uint8Array} view to the buffer like before https://crrev.com/c/1508352. Also, the returned view does not need to be another copy of the bytes, it can really just be a view. As a follow-up, this requires the test-only DeserializeWasmModule runtime method to receive the wire bytes as Uint8Array, and also requires the {IsWasmCompileAllowed} callback to handle {ArrayBufferView} (like chromium's version already does).

The regexp interpreter holds several unhandlified references to heap objects, and is thus within a DisallowHeapAllocation scope. But there are two situations in which we can and do allocate safely: 1. When creating & throwing a stack overflow exception. The interpreter aborts afterwards, and thus possible-moved objects are never used. 2. When handling interrupts. We manually relocate unhandlified references after interrupts have run. This CL explicitly allows allocations on stack overflows. Isolate::StackOverflow allocates heap objects.

We want to allocate feedback vectors lazily in lite mode. To do that, we should create closures with the correct feedback cell. This cl allocates feedback cell arrays to hold these feedback cells in lite mode. This cl also modifies the compile lazy to builtin to expect these arrays in the feedback cell. Drive-by fix: InterpreterEntryTrampoline no longer has argument count in a register. So updated comments and removed unnecessary push/pop of this register.

... similar to how we do this in native irregexp code, i.e. handle interrupts on each backtrack. Unhandlified references into the code ByteArray and the subject String object are updated after a potential GC. Since interrupts may change the subject string's representation, the interpreter is now called in a loop to handle retries.

According to the wasm js-spec, the table index can be uint32. The implementation in our implementation expected an int though. We did not check for the int overflow. I replaced the throwing of the exception in WasmTableObject::Get to use the ErrorThrower instead of throwing the exception with Isolate::Throw directly. The reason is that I see with other CL's that I have to throw several errors, and I don't want to introduce a new message and MessageId for every error. Moreover, the ErrorThrower is a standard way in wasm to throw errors. It feels right to throw the error the same way here.
