match lowering: handle or-patterns one layer at a time

`create_or_subcandidates` and `merge_trivial_subcandidates` both call themselves recursively to handle nested or-patterns, which is hard to follow. In this PR I avoid the need for that; we now process a single "layer" of or-patterns at a time.

By calling back into `match_candidates`, we only need to expand one layer at a time. Conversely, since we always try to simplify a layer that we just expanded (thanks to https://github.com/rust-lang/rust/pull/123067), we only have to merge one layer at a time.
