Reviewed by Geoffrey Garen.

The regression was due to the ENABLE_LLINT_C_LOOP flag not being included
in the build of the WebKit and WebKit2 components. As a result, some fields
in JSC::VM were ifdef'ed out in WebCore and JSC, but not in WebKit and
WebKit2. This resulted in VM::m_initializingObjectClass having 2 different
offsets depending on whether it is accessed from WebCore and JSC or from
WebKit and WebKit2, and chaos ensued.

This issue will manifest when we pass --cloop to build-webkit.
The fix is simply to add ENABLE_LLINT_C_LOOP to FEATURE_DEFINES for WebKit
and WebKit2.
