Original change's description:
> [wasm] Move the ModuleEnv to compiler and make it immutable.
> 
> This CL (finally) makes the contract between the compiler and the module
> environment clear. In order to compile a function, the caller must provide
> an instance of the compiler::ModuleEnv struct, which contains references
> to code, function and signature tables, memory start, etc.
