--- Comment #1 from chrbr at gcc dot gnu.org ---
Found this when fixing target/65837:

builtins should have a global scope. but this unmask a few other failures,
mostly with the hooks TARGET_VECTORIZE_PREFERRED_SIMD_MODE that return wrongs
values for global variables.

The problem is that TARGET_NEON is false for global scopes decls, although the
types were known.
