<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/197379">r197379</a> - Add new MethodTable method to get an estimated size for a cell
https://bugs.webkit.org/show_bug.cgi?id=154838
Patch by Joseph Pecoraro <pecoraro@apple.com> on 2016-02-29
Reviewed by Filip Pizlo.
The new class method estimatedSize(JSCell*) estimates the size for a single cell.
As the name implies, this is meant to be an approximation. It is more important
that big objects report a large size, then to get perfect size information for
all objects in the heap.
Base implementation (JSCell):
- returns the MarkedBlock bucket size for this cell.
- This gets us the object size include inline storage. Basically a better sizeof.
Subclasses with "Extra Memory Cost":
- Any class that reports extra memory (reportExtraMemoryVisited) should include that in the estimated size.
- E.g. CodeBlock, JSGenericTypedArrayView, WeakMapData, etc.
Subclasses with "Copied Space" storage:
- Any class with data in copied space (copyBackingStore) should include that in the estimated size.
- E.g. JSObject, JSGenericTypedArrayView, JSMap, JSSet, DirectArguments, etc.
Add reportExtraMemoryVisited for UnlinkedCodeBlock's compressed unlinked
instructions because this can be larger than 1kb, which is significant.
This has one special case for RegExp generated bytecode / JIT code, which
does not currently fall into the extra memory cost or copied space storage.
In practice I haven't seen this grow to a significant cost.
