        Some heap refactoring
        https://bugs.webkit.org/show_bug.cgi?id=61704

        SunSpider says no change.

        * JavaScriptCore.exp: Export!

        * heap/Heap.cpp: COLLECT_ON_EVERY_ALLOCATION can actually do so now.

        (JSC::Heap::Heap): Changed Heap sub-objects to point to the heap.

        (JSC::Heap::allocate): Changed inline allocation code to only select the
        size class, since this can be optimized out at compile time -- everything
        else is now inlined into this out-of-line function.

        No need to duplicate ASSERTs made in our caller.

        * heap/Heap.h:
        (JSC::Heap::heap):
        (JSC::Heap::isMarked):
        (JSC::Heap::testAndSetMarked):
        (JSC::Heap::testAndClearMarked):
        (JSC::Heap::setMarked): Call directly into MarkedBlock instead of adding
        a layer of indirection through MarkedSpace.

        (JSC::Heap::allocate): See above.

        * heap/MarkedBlock.cpp:
        (JSC::MarkedBlock::create):
        (JSC::MarkedBlock::MarkedBlock):
        * heap/MarkedBlock.h: Changed Heap sub-objects to point to the heap.

        * heap/MarkedSpace.cpp:
        (JSC::MarkedSpace::MarkedSpace):
        (JSC::MarkedSpace::allocateBlock):
        * heap/MarkedSpace.h:
        (JSC::MarkedSpace::allocate): Updated to match changes above.
