Original change's description:
> [destructuring] Elide coercible check for simple keys
>
> Simple object destructuring, such as `let {a,b} = o`, is less efficient
> than the equivalent assignments `let a = o.a; let b = o.b`. This is
> because it does a nil check of `o` before the assignments. However, this
> nil check is not strictly necessary for simple (i.e. non-computed) names,
> as there will be an equivalent nil check on the first access to o in
> `o.a`. For computed names the computation is unfortunately obervable.
>
> So, we can elide the nil check when the first property (if any) of the
> destructuring target is a non-computed name. This messes a bit with our
> error messages, so we re-use the CallPrinter to also find destructuring
> assignment based errors, and fiddle with the error message there. As
> a side-effect, we also get out the object name in the AST, so we can
> output a slightly nicer error message.
