I know this is another way to do it but is it really better? I think using Filecheck can easily get confusing, so matching two simple strings seems like a better idea, in general, compared to matching one more complicated one (especially since the tools' output is in flux and we don't want big parts of tests suddenly failing because of a change in the output format of a tool). I copied that idea from other Arm assembly tests in there.
