Original change's description:
> [wasm] Add support to allocate in a specific code region
> 
> For multiple code spaces with multiple jump tables, we need to allocate
> the space for the jump tables within specific regions (the new code
> spaces) so they are within reachable distance.
> This CL adds support for that, and uses it for the first jump table.
