The problem here is after r16-101, the 2 functions containing alloca/VLA
start to be cloned and then we un-VLA happens in using_vararray so this
is no longer testing what it should be testing.
The obvious fix is to mark using_vararray and using_alloca as noclone too.
Pushed as obvious after a quick test to make sure it is now working.
