I think this LGTM, just a quick question for clarity. Although the test contains a conditional branch on a constant value (so, a round-about unconditional branch), I'm right in thinking we might hoist instructions here even if there are (runtime-) conditional branches too?

If so all good. If not then I think dropping is probably still correct, but I'd need to work harder to convince myself of that.
