Make sure IfBuilder::Return clears the current block. · 39e9a903

mstarzinger@chromium.org authored May 29, 2013

This is a follow-up to an earlier bugfix. It doesn't yet trigger any
known bugs but is a safety precaution since IfBuilder usage increases.

Fix handle zapping interaction with NoHandleAllocation. · bc9bc0de

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.
