Original issue: https://codereview.chromium.org/15331002/

Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.

IsObserved now checks for JSReceiver and returns false rather than crashing.

CL breaks mips, since the deoptimizer in Deoptimizer::DoTranslateCommand(...) does not convert smis passed to the stub via a0.

known bugs but is a safety precaution since IfBuilder usage increases.

This makes sure that closed handle scopes are properly zapped even if an
enclosing NoHandleAllocation shrunk the limit. It also unifies the code
that performs scope closing for internal and external handle scopes.

This gets rid of more places where Persistent handles are copied
(see crbug.com/236290 ).

Transition plan: after this CL, Blink will be modified to work both with and
without the #define, then the #define will be removed from V8.

The corresponding Blink side changes are in https://codereview.chromium.org/15670010/ .
