This doesn't enable the warning yet, but adds V8_FALLTHROUGH annotations in enough places so that v8 can build with the warning on on my linux box.

When decoding a br_table instruction, check each br target only once, even if it appears several times in the break table. Also, only mark the merge points as reached after calling the interface method. This is consistent with the behaviour for br and br_if, and is needed for implementing Liftoff correctly. Drive-by: Remove {BreakTo} method which hides trivial functionality behind a non-trivial method name. Drive-by^2: Remove redundant reachability tests.

The call to isolate_->AdjustAmountOfExternalAllocatedMemory in WasmCodeManager::FreeNativeModuleMemories can cause a GC, which can indirectly call WasmCodeManager::FreeNativeModuleMemories again. It seems that this recursive call can cause memory to be deallocated twice. With this CL we clear the list of owned_memory after all entries were deallocated so that we cannot deallocate them again. I think this CL fixes a crash we saw on ChromeCrash. I don't know how to reproduce the issue though, or how to write a test for it.

In some workloads the Unmapper could reach kMaxUnmapperTasks at which point it wouldn't start any new tasks and not free any more memory until the next major GC.

The WasmModuleObjectBuilder was the first interface for streaming compilation of WebAssembly. Over time we realized that the interface is insufficient, and we introduced the WasmModuleObjectBuilderStreaming class, which is used now for streaming compilation. Since the WasmModuleObjectBuilder was never fully functional, I think it is okay to remove it without a deprecation period.

CSA::EmitElementStore used to bail out (IC miss) via CSA::CheckForCapacityGrow when the capacity hits the new space limit, causing the store IC to go megamorphic in my example (see referenced bug). With this CL, we do what TF'ed code does already: call into Runtime::kGrowArrayElements (in this situation), thus staying monomorphic.
