This CL fixes a bug where execution would continue on a fast-path
even though a previous recursion step bailed to the slow path. This
would allow possibly illegal loads that could leak to JS.
Drive-by change: Instead of bailing to the slow-path on each recursion
step, we now bail completely and start the slow-path afterwards.
