progress towards cross-architecture bootimage builds

Browse Source 
This monster commit is the first step towards supporting
cross-architecture bootimage builds.  The challenge is to build a heap
and code image for the target platform where the word size and
endianess may differ from those of the build architecture.  That means
the memory layout of objects may differ due to alignment and size
differences, so we can't just copy objects into the heap image
unchanged; we must copy field by field, resizing values, reversing
endianess and shifting offsets as necessary.

This commit also removes POD (plain old data) type support from the
type generator because it added a lot of complication and little
value.
