// ASM stream — `asm { … }` parses + validates the full rich shape: named value
// outputs (`[quot] "={rax}" -> u64`), register-pinned inputs, and a
// `clobbers(.…)` clause, all accepted. This is a MULTI-output (tuple-returning)
// asm, which is deferred to Phase E — so lowering bails LOUD + named with the
// specific "Phase E" diagnostic (single-output asm already runs; see 1645).
// Called from `main` so lowering reaches the asm body (lazy lowering skips
// uncalled functions).
