The Node-hosted CLI emits with an empty target triple (the host), while
the native CLI passes its toolchain's triple. Inline truncation keyed on
the triple text alone, so on x86-64 Linux the Node seed emitted
llvm.trunc and the native compiler emitted the inline sequence, and the
native bootstrap's LLVM comparison with the Node seed failed
(self-hosting-native-driver, rebuild-emit). An empty triple now means
the host architecture, as it already does for executable TLS; WASI keeps
the intrinsic. The DataView emission test accepts either truncation
form, since it runs on hosts of both kinds.
