Eric Holk 19617ec0c3 Reland "[wasm] Always enable guard regions on 64-bit platforms" 
This is a reland of ad221d144a

Original change's description:
> [wasm] Always enable guard regions on 64-bit platforms
> 
> 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.
> 
> This is a reland of https://crrev.com/c/985142.
>
