This change makes full 8 GiB guard regions always enabled on 64-bit platforms. Additionally, since all Wasm memory allocation paths have some form of guard regions, this removes and simplifies most of the logic around whether to enable guard regions.

For the wasm2js wrappers we have an optimization to call a JavaScript function directly if the signature of the JavaScript function matches the signature of the WebAssembly import. However, we are not supposed to do this optimization if the imported function is a constructor, because constructors can only be called with `new`. With this CL we do not apply this optimization when the imported function is a constructor.
