Message:

Rename MarkedAllocator to BlockDirectory and AllocatorAttributes to CellAttributes
https://bugs.webkit.org/show_bug.cgi?id=181543

Rubber stamped by Michael Saboff.
Source/JavaScriptCore:

In a world that has thread-local caches, the thing we now call the "MarkedAllocator" doesn't
really have anything to do with allocation anymore. The allocation will be done by something
in the TLC. When you move the allocation logic out of MarkedAllocator, it becomes just a
place to find blocks (a "block directory").

Once we do that renaming, the term "allocator attributes" becomes weird. Those are really the
attributes of the HeapCellType. So let's call them CellAttributes.
