Free memory is marked as inaccessible, which means that it contains a zap value and is poisoned in ASAN builds. Before writing the unlinked sentinel, we must unpoison the memory area in ASAN builds.

The wasm interpreter was always single-threaded, and there are no plans to change this. Still, there was a concept of threads, but with the hard-coded constraint that there is always exactly one of them. In order to clean up the code, and as a preparation to remove more unneeded functionality before moving the interpreter over to the test directory, this CL removes the concept of threads and merges the {ThreadImpl} class into {WasmInterpreterInternals}. Drive-by: Remove the dead {GetFrameCount} method.

Clemens Backes authored
Most interface calls are preceded by a reachability check, such that we only generate code if the current instruction is actually reachable. This is particularly important for Liftoff (TurboFan would throw out dead parts of the graph anyway). In order to speed up this check, this CL introduces a boolean flag directly on the {WasmFullDecoder}. This avoids checking whether an error has been set *plus* checking the reachability of the top-most control block. This provides 5-6% speedup on Liftoff compilation locally.

All these functions need to do is just write the value to the memory, but EmitHelper will do something more than this, EmitHelper will check if it need generate trampoline code while code generating and it will insert trampoline code at current pc offset, this means there maybe have trampoline code between two consecutive dd()'s target memory(pc), this is not we want.

Under some circumstances, Wasm is trying to log code for which the wire bytes are not fully loaded yet. This can happen during streaming compilation when a few functions are already fully compiled but the engine is still streaming the remaining functions. If the profiler now kicks in, it will attempt to log these freshly compiled functions. As these functions will not be executed before the module is fully compiled, we can simply defer the logging in this case.
