The problem was that in AsyncCompileJob::FinishModule we allocate a handle, but when this function is called from streaming compilation, then there was no HandleScope around AsyncCompileJob::FinishModule. This issue was fixed in another CL, https://crrev.com/c/1172357. This CL is just a rebase of the original CL. Original change's description: > [wasm] Implement the new API for WebAssembly.instantiateStreaming > This is the second V8 CL to refactor WebAssembly.instantiateStreaming to > make it spec compliant again. The design doc where the whole change is > discussed is available in the tracking bug. The tracking bug also > references prototype implementations of the whole change, which includes > the changes in this CL.

This was an oversight from the previous CL. It doesn't really matter with the current code generation pattern, since the upper bits of the index will always be zero, but that might change in the future.

This adds support for unaligned load/store access to the DataView backing store and uses byteswap operations to fix up the endianess when necessary. This changes the Word32ReverseBytes operator to be a required operator and adds the missing support on the Intel and ARM platforms (on 64-bit platforms the Word64ReverseBytes operator is also mandatory now). This further improves the performance on the dataviewperf.js test mentioned in the tracking bug by up to 40%, and at the same time reduces the code complexity in the EffectControlLinearizer.

The DataView access methods can use the neutering protector to avoid introducing an explicit check into the optimized code to see if the backing store was neutered. Instead the optimized code has an implicit dependency on the global neutering protector which gets invalidated when the first array buffer is neutered (globally). We use the same trick for typed arrays already.

In {WasmEngine::DeleteCompileJobsOnIsolate} (triggered on isolate teardown), we are deleting the {AsyncCompileJob} with the expectation that this cancels all background compilation. Since the introduction of the CompilationState, this is not true any more. The call to {CompilationState::Abort} is missing. This CL fixes this by moving the logic from {AsyncCompileJob::Abort} to {~AsyncCompileJob}, since the former calls the latter anyway.

With the origin trial for WebAssembly threads, threads can be turned on and off by the embedder depending on the context we are currently in. With this CL we call the embedder callback stored on the isolate to determine whether threads are enabled in the current context or not. Design decision: I decided to extend the {WasmFeaturesFromIsolate} function to ask the embedder if WebAssembly threads are enabled. This is the function which defines dynamically which features are turned on. It would be awkward to have two such functions, one which calls the embedder and one which does not. A downside is that in WasmJs::Install the embedder does not seem to be ready to be called. That's why I changed the code there to call {WasmFeaturesFromFlags} instead.
