Seems like we have most of the PowerPC backend owners on review already (https://github.com/llvm/llvm-project/blob/main/llvm/Maintainers.md#powerpc-backend).

Please could one of the reviewers advise when they might be able to take a look, and/or what @Gelbpunkt should do to move this forward.

@Gelbpunkt please add to the PR description any conclusions from the conversation so far, or supporting evidence, for doing this change. So that reviewers have all the information ready if/when they do look at this.

(maybe it's fine as is, but I'm not a PowerPC expert so not judging)
