// ASM stream Phase 2 — `-> @place` write-through output. An asm result can be
// STORED through a place (a local / struct field) instead of returned: the
// place output does NOT join the result tuple. Here one value output is
// returned (into `main_val`) while a second is written through `@other`. The
// two are combined to 42. Read-write (`+`) and indirect (`*`) place outputs are
// not yet implemented (rejected at lowering). aarch64-pinned; ir-only elsewhere.
