// Pack-fn (or any comptime-param fn) with a block body containing
// an explicit `return X;` lowers to clean IR — the inline-return
// path stores into a dedicated result slot and branches to the
// shared `ret_done` block instead of emitting a `ret` inside the
// caller's basic block. Without that, LLVM's verifier rejected the
// IR with "Terminator found in the middle of a basic block".
//
// Surfaced by the variadic heterogeneous type packs feature (step
// 1 made `..$args` parseable, so the simplest pack-fn smoke test
// exercised the bug). The root cause is broader than packs: ANY
// comptime fn with `is_comptime` params, a non-void return, and a
// block body with `return X;` had the same crash. `format`/`print`
// use arrow form (`=> expr`) or `#insert`-only bodies, so the bug
// was invisible until pack-fn bodies surfaced it.
//
// Once fixed, calling foo() reaches the body's `return 42;`, the
// inliner stores 42 into a result slot, the caller loads it as the
// inline value, and main prints "42".
