I'm trying to understand the goal here: is the intention to move codegen passes to NPM? I'd imagine there is a RFC for that, is this it? https://discourse.llvm.org/t/rfc-introducing-classes-for-the-codegen-driven-by-new-pass-manager/55877

I'm assuming you tried the change with the ML bits enabled? I.e. like the ml-opt-{dev|rel|devrel}-x86-64 bots do?

(I'd appreciate waiting for a LGTM from @boomanaiden154 or me, but please note next week is a generally a slow week in the US because the end of it is a bank holiday. I am out, but will pick this up the Monday after)
