Message:

Add zombies to JSC
​https://bugs.webkit.org/show_bug.cgi?id=32103

Reviewed by Gavin Barraclough.

Add a compile time flag to make the JSC collector replace "unreachable"
objects with zombie objects. The zombie object is a JSCell subclass that
ASSERTs on any attempt to use the JSCell methods. In addition there are
a number of additional assertions in bottleneck code to catch zombie usage
as quickly as possible.

Grrr. Argh. Brains.
