So on x86_64, we test to see if you have the right vector unit before
running those tests? The same thing was true on powerpc (and I think
aarch64 does the same for SVE now too). The reason why I am asking is
that I would need to run the testsuite using the simulator as setup
for the RISCV ISA I am using rather than the one with everything on.
So does the RVV runtime testsuite tests to see if you can run RVV
before running them (or running them and return they passed)?
