marja 51685002a6 Revert of Put Scopes into temporary Zone (patchset id:220001 of https://codereview.chromium.org/2193793002/ )
Reason for revert:
Broke Node.js tests (test-require-dot etc.)

Original issue's description:
> Put Scopes into temporary Zone
>
> When parsing a eagerly-parsed-but-lazily-compiled function, we
> used to put some of its AST nodes into a discardable Zone. This
> CL puts the function Scope, its inner Scopes and the related AST
> nodes (Declarations, VariableProxys) into the temporary Zone
> too. This reduces peak memory usage and enables future work to
> keep the temporary Zone around for later compilation.
