Field layout in class Arguments is incompatible w\ 64-bit archs.
The length_ field must be defined as intptr_t rather than int. This is
due to the fact that we place native argc/argv values into stack slots
(via SetFrameSlot) and then interpret the slots as a an instance of
Arguments class.
Little endian architectures get 'lucky' that the layout happens to work
with implicit padding. Big endian is not as lucky.
See Runtime_ArrayConstructor for an example.

Use a cheaper RecordWriteForMap() to update the

in RecordWriteField() when we statically know that
