I've reverted this PR, because it landed without approval. Please do not reuse old PRs to avoid this kind of confusion, where approvals from a completely different earlier patch keep hanging around, even though nobody actually reviewed the new implementation in any detail.

Before resubmitting this, I'd recommend creating a PR for the CallBrPrepare -> InlineAsmPrepare rename first. It looks like the changes end up being sufficiently substantial that git can no longer recognize this as a file rename and shows it as a delete + create instead, which makes the diff hard to review.
