The only way I can think of is to implement some assembly functions that
explicitly test the layout of calling conventions. Then write C functions
that work with them: dispatch and receiver tests have to be written. We
should probably have regress/abi/arch/arm (or something like that) with
tests for this. Apart from anything else, such a set of tests would make
importing future compilers much easier.

Well, we certainly don't have stack alignment implemented yet. I think we
sort of have VFP endian floats (Ben sort of hacked that up), but I haven't
tried it against the full implementation I'm working on.
