Yang Guo 3857b44e69 Introduce SimpleNumberDictionary. 
This is somewhat of a revival of what used to be
UnseededNumberDictionary. The difference to NumberDictionary is that
each entry only has two fields (no field for property details) and there
is no header field for a bitfield.

The reason for this change is memory regression introduced when we
removed UnseededNumberDictionary (6e1c57eaa9). We now use
SimpleNumberDictionary for
- slow template instantiation cache
- code stubs table
- value serializer map
- stack frame cache
- type profile source positions
