[PATCH 3/3] treewide: Update LLVM Bugzilla links

Nathan Chancellor
2024-01-09T22:16:54Z

LLVM moved their issue tracker from their own Bugzilla instance to
GitHub issues. While all of the links are still valid, they may not
necessarily show the most up to date information around the issues, as
all updates will occur on GitHub, not Bugzilla.

Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number. Thankfully, LLVM maintains this mapping
through two shortlinks:

https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>

Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up
to date information. Each migrated issue links back to the Bugzilla
entry, so there should be no loss of fidelity of information here.
