This reverts commit 23b2d571a7.
Reason for revert: Breaks the V8 roll https://ci.chromium.org/ui/p/chromium/builders/try/linux-rel/1000394/
Original change's description:
> Reland "[heap] Store size with invalidated object"
>
> This is a reland of commit 5d235def26
>
> The previous version of this CL got reverted because the cached
> size of an invalidated object wasn't up-to-date when performing a GC.
>
> Not all size changes go through NotifyObjectLayoutChange, so
> https://crrev.com/c/3607992 introduced NotifyObjectSizeChange as a
> bottleneck for object size changes/right-trimming. This method is
> now used to update the size of invalidated objects.

> Original change's description:
> > [heap] Store size with invalidated object
> >
> > When updating pointers during a full GC, a page might not be swept
> > already. In such cases there might be invalid objects and slots recorded
> > in free memory. Updating tagged slots in free memory is fine even though
> > it is superfluous work.
> >
> > However, the GC also needs to calculate the size of potentially dead
> > invalid objects in order to be able to check whether a slot is within
> > that object. But since that object is dead, its map might be dead as
> > well which makes size calculation impossible on such objects. The CL
> > changes this to cache the size of invalid objects. A follow-up CL will
> > also check the marking bit of invalid objects.
