Before 983eec8979, RewritableExpressions
which had been queued for destructuring assignment rewriting but which
turned out to be part of a binding pattern in arrow function parameters
would be silently ignored by the PatternRewriter. After that CL, they
failed with a DCHECK.
This patch reverts to the previous behavior, with a TODO to handle this
in a better way by dequeuing RewritableExpressions that turned out
to be part of an inner arrow function.
