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.
