I have added two. There are two cases no-instr*-no-instr2 where linux version produces zero size prof data vs non-existing file (making changes to unlink file can be tricky) -- so adding a test here can be tricky. As this is not the expected using case anyway, existing testings already cover the expected behavior (build, run etc), I will leave this as it is .
