Change StoreField to StoreTaggedField, which, similar to the move of
LoadField to LoadTaggedField, operates on an offset and not a full Smi
handler. Then, add support for stores to a property array by emitting a
LoadTaggedField of the property array.

As a drive-by, fix support for const fields and HeapObject fields with
a class field type.
