Since the mutability of HeapNumbers is determined by their owning object's descriptor array, we can remove the MutableHeapNumber type entirely, at the cost of a few fewer DCHECKs and a couple of TODOs to use the descriptor array information. This is a necessary step towards a follow-up which allows in-place Double -> Tagged transitions Design doc: https://docs.google.com/document/d/1VeKIskAakxQFnUBNkhBmVswgR7Vk6T1kAyKRLhqerb4/ Bug: v8:9606 Change-Id: I13209f9c86f1f204088f6fd80089e17d956b4a50 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1743972 Commit-Queue: Leszek Swirski <leszeks@chromium.org> Reviewed-by:

This avoids leaving the heap in an invalid state if a GC occurs during population of the cloned property array, as is done in other IC builtins.

Change the macros added in bf84766a to only do the hard work if FLAG_unbox_double_fields is unset (otherwise, they will attempt to dereference raw float64s, which is bad!) Also adds a write barrier in CopyPropertyArrayValues for each store if it's possible that a MutableHeapNumber is cloned.
