1. deps: fix async await desugaring in V8 …

   This is a backport of https://codereview.chromium.org/2672313003/. The
   patch did not land in V8 because it was superseded by another one but it
   is much easier to backport to V8 5.5, was reviewed and passed tests.
   
   Original commit message:
   
       [async await] Fix async function desugaring
   
       Previously we rewrote the return statement in an async function from
       `return expr;` to `return %ResolvePromise(.promise, expr),
       .promise`. This can lead to incorrect behavior in the presence of try-finally.
   
       This patch stores the `expr` of the return statement in a temporary
       variable, resolves and returns the promise at the end of the finally
       block.
