I noticed the other day that this link was redirecting, but I don't
think we want this change.

We use the PSTL as it was when we imported (i.e. forked) it. We don't
use whatever it's now part of.

A better link would be:
https://github.com/llvm/llvm-project/tree/master/pstl
which is the upstream for our code (even though we're shipping it and
LLVM isn't).
