Description of change

Enable support for standalone block statements.
Fixes #5576.

node 🙈 ₹ git:(upstream ⚡ bare-block) ./node
> { var x = 3; console.log(x); }
3
undefined
> {}
{}
> { x:1, y:"why not", z: function() {} }
{ x: 1, y: 'why not', z: [Function] }
>

For the ambiguous inputs like { x }, the existing REPL behaviour (ES6 literal shorthand) is preserved (prefers expression over statement).

* npm: Upgrade to v3.8.3. Fixes a security flaw in the use of
authentication tokens in HTTP requests that would allow an attacker to
set up a server that could collect tokens from users of the command-line
interface. Authentication tokens have previously been sent with every
request made by the CLI for logged-in users, regardless of the destination
of the request. This update fixes this by only including those tokens
for requests made against the registry or registries used for the
current install. (Forrest L Norvell)
