Although clang didn't implement it and there are old test case uses this style, I think it might be better to split into files. @urnathan how do you think about this?
I see this in the Tony tables, but OTOH I cannot exactly see where the wording forbids it - in fact it permits preprocesssor directives before the import (including in the example in 5.7)... perhaps I'm misreading.

This way of writing the test cases does make them much easier to manage (and for a reader to see the intent) - of course, if we should split into files - then that is what we should do.
