Regression testing wouldn't have caught the problem, unless Carl had
done so on power10.  "dg_do compile" tests don't run the assembler,
and "dg_do run" tests with "dg_require_effective_target power10_hw" do
nothing at all if not on power10 hardware.  The single test that might
have caught the problem, vec-splati-runnable.c wasn't even compiled.
That's why I submitted
