So this no longer runs it for p7, and it also doesn't run it for cpus
after p9 anymore. Could you change it to be a test for p9 and above,
and one for before p9? Does that work?

-mvsx is implied by power8 (or power7, already).
You don't need the test for Darwin: Darwin never has VSX, already (and
if it somehow would ever get support for it, we'd want this test to run
for it).

We usually write this as scan-assembler-not, but this works just fine
as well. Whichever you prefer.
