--- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Rather than muck around with costing, all that's goofy here is we don't
optimize VEC_EXTRACT of an element out of a uniform vector.  Fixing that (in
match.pd) simplifies things enough that there isn't any vector code left as we
leave gimple.
