[JSC] Object constructor need to be aware of new.target
https://bugs.webkit.org/show_bug.cgi?id=157196
Reviewed by Darin Adler.
Object constructor should be aware of new.target.
When the new.target is specified, we should store it.prototype to the newly created
object's [[Prototype]].
* runtime/JSGlobalObject.cpp:
(JSC::JSGlobalObject::init):
(JSC::JSGlobalObject::visitChildren):
Take the design that caches the structure used for empty object.
This structure is also used in constructEmptyObject frequently.
* runtime/JSGlobalObject.h:
(JSC::JSGlobalObject::objectStructureForObjectConstructor):
* runtime/ObjectConstructor.cpp:
(JSC::constructObject):
(JSC::constructWithObjectConstructor):
(JSC::callObjectConstructor):
* runtime/ObjectConstructor.h:
(JSC::constructEmptyObject):
Construct the object by using the plain structure that is also used in the ObjectConstructor.
* tests/stress/object-constructor-should-be-new-target-aware.js: Added.
