hexagon: adapt test for upstream output changes

The output of IR formatting changed slightly in upstream rev
a0bc67e
(https://reviews.llvm.org/D123096). I'm not actually sure what any of
that means, as I don't even know what hexagon is in this context, but
this change allows the test to pass on both old and new LLVMs.
