I may be confused, but you're not making use of the "llp64" 
effective target, there instead excluding/including lp64 / 
ilp32 in sets that not obviously mean "exclude LLP64".

To wit, how is "! ilp32" -> "lp64" and "ilp32" -> "! lp64" 
expressing "! llp64"?

OK, although in general I think would be good to use
{ target { ilp32 || llp64 } } for this kind of thing.

No need to change this patch though, just saying for the future.

Thanks for reviewing, how does the "ilp32" or "llp64" before the curly 
target brackets work?

That's just a free-form string, to make the test name unique.
