I think this is a very important bug for 3.1.  I think if we don't
come up with the cleanest fix, we should at least check in the
available fix on the branch.

I looked at writing the proposed fix tonight.  It's not clear to me
how it should work.  Do we want a new function like
ffi_promoted_type()?  The idea being that we would pass in a type,
like FFI_TYPE_UINT8, and then ffi would return the promoted type.  Do
we have a table of the rules for all the supported platforms?  I
suppose the default implementation should just assume that integral
types narrower than the platform's `int' should promote to `int'.
