PNaCl wire format: Remove the top-level DATALAYOUT record
PNaCl only supports a fixed data layout, so treat this as implicit in
the pexe file.
Add the data layout field back at read time, to prevent accidentally
using any architecture-specific backend data layout when translating,
and to ensure that any IR passes that use the data layout work
correctly.
