             nThis:


currentThreadStackBase() is currently a static function in
JavaScriptCore/runtime/Collector.cpp

The GObject DOM binding will implement a conservative stack-only GC for wrapper
objects and C strings and needs a way to get the current thread stack base in
the marking phase.

Since this code has delicate platform-specific conditionals and isn't
JSC-specific, it's best split out and moved into WTF where it can be reused.
Introducing a new header for GC utility functions will also pave the way for
sharing more of the JSC collector implementation with DOM bindings and WebKit
API layer code which could benefit from garbage collection.
