This CL enables the auto-roll script to close and reopen the tree when pushing.

Modifies an auto-roll test so that the push-to-trunk part is executed in order to test the new tree control feature.

This is done similar to weak embedded objects in optimized code (r17102). The
reference from optimized code to a cell is treated weakly in marking visitors
if the cell points to a JSObject. After marking we iterate over all cells
embedded in optimized code. If a cell is not marked but its value is marked,
then we revive the cell by marking it. Otherwise, the cell value is dead, so
we mark the code for deoptimization.

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

This unifies the names used for floating point ABI abstraction across
ARM and MIPS and makes them more comprehensible. Note that in the
underlying implementation, ARM doesn't care about the argument/result
distinction, while MIPS does, but we want to abstract from that, too.
