Fix for: <rdar://problem/6918095> REGRESSION: jQuery load() issue (25981),
and also an ASSERT failure on ​http://ihasahotdog.com/.

When overwriting a property on a dictionary with a cached specific value,
clear the cache if new value being written is different.

• JavaScriptCore.exp:

Export the new symbols.

• jit/JITStubs.cpp: (JSC::JITStubs::cti_op_get_by_id_method_check_second):

Close dictionary prototypes upon caching a method access, as would happen when caching
a regular get_by_id.

• runtime/JSObject.h: (JSC::JSObject::propertyStorage): (JSC::JSObject::locationForOffset):

Make these methods private.

(JSC::JSObject::putDirectInternal):

When overwriting a property on a dictionary with a cached specific value,
clear the cache if new value being written is different.

• runtime/Structure.cpp: (JSC::Structure::despecifyDictionaryFunction):

Reset the specific value field for a given property in a dictionary.

(JSC::Structure::despecifyFunctionTransition):

Rename of 'changeFunctionTransition' (this was already internally refered to as a despecification).

• runtime/Structure.h:

Declare new method.
