For a test in particular I think the question is whether the change can
somehow negatively affect the test itself; and maybe secondarily whether
some plausible and/or planned future change would break the test.

If not then it seems fine to move forward.

Generally I think we'd be better off eliminating these assembly tests in
favor of something like the test suite's DWARF assembler, though I
didn't look to see whether this one would qualify.
