Looks good to me. (You can probably use build_nonstandard_integer_type()
instead of lang_hooks.types.type_for_mode).

I am not sure I understand the question. Are you asking how to check that it
gets vectorized only on i?86/x86_64? If so, you need a new proc in
lib/target-supports.exp (something like vect_cond_mixed_types).
