Note I'm mostly trying to capture [the docs](https://docs.google.com/document/d/1RRYMm42osyqhI2LyjrjockYCutQ5dOf8Abu50kTrkX0/edit?resourcekey=0-kHyqOESbOHmzZphUbtLrTw&tab=t.0) as they exist today, not fixing issues with the docs. I think the doc itself hasn't changed much lately (i.e., for months). Trying to organize it a little better though, particularly so that it shows up reasonably when looking in github or the website. --------- Co-authored-by: Geoff Romer <gromer@google.com>

Overview
Lowering takes the SemIR and produces LLVM IR. At present, this is done in a single pass, although it's possible we may need to do a second pass so that we can first generate type information for function arguments.
Lowering is done per SemIR::InstBlock. This minimizes changes to the
IRBuilder insertion point, something that is both expensive and potentially
fragile.
