// arr_u16_store_test — [N]u16/[N]i16 array-literal init stores MOVW per slot.
// Migrated from test/wcc/914_arr_u16_store_run.c. Pre-fix a [4]u16 init emitted
// overlapping MOVQ stores (accident-corrected for some values); the fix dispatches
// a proper MOVW per 2-byte slot (op chosen by esz, not signedness). cstage
// build+run was T1; cs==ww .s byte-id rides T2 (test-lang-byteid). The full_init
// row asserts each element to catch any value drift; the [4]u8 control pins the
// MOVB path is unchanged; i16_signed pins the dispatch is not signedness-gated.
