Leszek Swirski 489e7deb7e [object] Remove MutableHeapNumber
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
