[PATCH] D152226: [FunctionAttrs] Propagate some func/arg/ret attributes from caller to callsite (WIP)

[Noah Goldstein via Phabricator via llvm-commits]

goldstein.w.n added a comment.

llvm-test-suite passes with this patch enabled.
But note: **There currently some failing clang tests**.
Most of them look benign (just need to propagate a few attributes to a few thousand places),
but I was hoping there is a way to auto-regenerate them before going through laboriously by hand.
All the ones that can be auto regenerated I updated + a few by hand before thinking better of it.
Currently the list of failing tests in the llvm-project with all projects enabled using `ninja check-all` is:

Is there a way to autoregen them, some of them need a few thousand changes (just adding `noundef` for the most part) that hopefully doesn't need to be done by hand.
