Closed generator returns a completed object instead of throwing a error
...
From ES6 rev20 draft, closed generator returns completed object (the
value is `undefined` and done is `true`).
Since a error thrown in generator is propagated to the caller without
setting status of a thrown generator to "completed", once a generator is
suspended by a error, status becomes "executing" forever. This is filed
as v8:3096

Fixed Lithium environment generation bug for captured objects (created
...
by escape analysis). Added several tests that expose the bug.
Summary:
LCodegen::AddToTranslation assumes that Lithium environments are
generated by depth-first traversal, but LChunkBuilder::CreateEnvironment
was generating them in breadth-first fashion. This fixes the
CreateEnvironment to traverse the captured objects depth-first.
Note:
It might be worth considering representing LEnvironment by a list
with the same order as the serialized translation representation
rather than having two lists with a subtle relationship between
them (and then serialize in a slightly different order again).
