Ensure: - builders always have a `bx` suffix; - backend basic blocks always have an `llbb` suffix, - paired builders and basic blocks have consistent prefixes.
`TerminatorCodegenHelper` has three methods `llblock`, `llbb`, and `lltarget`. They're all similar, but the names given no indication of the differences. This commit renames `lltarget` as `llbb_with_landing_pad`, and `llblock` as `llbb_with_cleanup`. These aren't fantastic names, but at least it's now clear that `llbb` is the lowest-level of the three and the other two wrap it.
- Rearrange the match in `llbb_with_landing_pad` so the `(Some,Some)` cases are together. - Add assertions to indicate two MSVC-only paths.
It has a single call site.
It's only ever used with shift operators.
