arch and include: update LLVM Phabricator links

Browse Source 
reviews.llvm.org was LLVM's Phabricator instances for code review.  It has
been abandoned in favor of GitHub pull requests.  While the majority of
links in the kernel sources still work because of the work Fangrui has
done turning the dynamic Phabricator instance into a static archive, there
are some issues with that work, so preemptively convert all the links in
the kernel sources to point to the commit on GitHub.

Most of the commits have the corresponding differential review link in the
commit message itself so there should not be any loss of fidelity in the
relevant information.
