[iOS] Upstream WebSafe{GCActivityCallback, IncrementalSweeper}IOS
https://bugs.webkit.org/show_bug.cgi?id=123049
Reviewed by Mark Hahnenberg.
Source/JavaScriptCore:
* heap/Heap.cpp:
(JSC::Heap::setIncrementalSweeper):
* heap/Heap.h:
* heap/HeapTimer.h:
* heap/IncrementalSweeper.h: Make protected and export CF-variant of constructor.
Removed unused include of header RetainPtr.h. Also forward declare class MarkedBlock
(we include its header in the .cpp file) and remove include for header wtf/HashSet.h
(duplicates the include in the .cpp).
* heap/MachineStackMarker.h: Export function makeUsableFromMultipleThreads(). We aren't
making use of this now, but we'll make use of it in a subsequent patch.
Source/WebCore:
* WebCore.xcodeproj/project.pbxproj:
* platform/ios/WebSafeGCActivityCallbackIOS.h: Added.
* platform/ios/WebSafeIncrementalSweeperIOS.h: Added.
