Forgot to say: this was previously posted as part of the AMD GCN
worker-partitioning series here:

  https://gcc.gnu.org/pipermail/gcc-patches/2021-March/566081.html

But I noticed that the worker-partitioning patches do not (now?) have to
be present for the tests in question to fail.

Thanks,

Julian
