When performing a shared allocation in a client we have checks for the AlwaysAllocateScope in both client and shared isolate slow allocation code paths. We need to enable both such that we don't fail with spurious OOM failures with GC stress bots. This change was already introduced with the reverted CL https://crrev.com/c/3422630. Land this as its own CL until that CL relands.

Verification code in HeapObject::set_map() is supposed to run on the main thread since object layout change is only supported on the main thread. There are some users of set_map() on background threads though, which resulted in crashes. Since those users all perform a safe map transition, we introduce a separate method for this purpose: HeapObject::set_map_safe_transition(). This method behaves just like set_map() but verifies that this is a safe map transition and not an object layout change and therefore can be used on background threads as well. This CL also adds a DCHECK to HeapObject::set_map() to ensure we run this method only on the main thread.

We introduce a new information type ForwardingIndex to be stored in the Name::Hash field (to be used in the future). To do so we use the 2 least significant bit to distinguish types of information stored in the hash field (in contrast to only bit 1 to distinguis integer indicies from "real" hashes). This motivated a refactor to use base::BitField for the hash field.

Changes: - Check the wrapped function's return types - Skip type checking of return types when importing a wrapper (and assert that the return type is externref) - Add special case for WebAssembly.Function.type of a WasmExportedFunction: it currently returns the signature declared by the module. Change the return type to externref if this is a stack-switching export.

We have two different kinds of GC prologues/epilogues. The user-exposed one in Heap and the internal one in LocalHeap. During parsing and in the JSON parser we were using the former. While this is definitely correct and at the time of implementation it was the only existing mechanism, I believe the internal callbacks are now a better fit for these use cases. Internal callbacks are simpler since they don't allow allocations, which allows us to run them during the GC safepoint. The user-exposed interfaces are allowed to allocate and are run either before or after the safepoint. Such allocations could cause recursive GCs, which is impossible for internal callbacks.

The web app owner who notified me about bugs v8:12112 and v8:12126 asked me a reasonable question: "how am I ever supposed to trust the retaining paths in the devtools, if the heap snapshot is generated by a different component than the actual marking code?". This change is my attempt to answer that question. If verification is enabled, the heap snapshot generator will visit each heap object with a realistic marking visitor to find all references from that object. It will then check that those references match the HeapGraphEdges in the snapshot. I also considered the idea that we could collect retaining information during the last GC cycle before taking the heap snapshot, or during an extra GC cycle immediately after. However, running the full GC provides the embedder with the opportunity to run arbitrary code (including JS) both before and after PerformGarbageCollection, so there is no clear guarantee that the heap state during the snapshot actually matches the heap state during marking.

TracedNode is used as backing node for v8::TracedGlobal (with destructor) and v8::TracedReference (no destructor). A future change adds concurrent marking for TracedReference which requires that the node stays around until the atomic pause to avoid synchronization with the concurrent marker. This change prepares TracedNode in prolonging the lifetime until the it is actively cleared ("sweeped") in the atomic pause. This allows for spuriously keeping alive a TracedNode for an additional GC cycle in the case the the node was destroyed while the marker is running. We maintain eager clearing of nodes where possible, i.e., outside of incremental marking.
