[C PATCH]: Vector type init

[Aldy Hernandez]

Hi Nathan.

Thanks so much for looking at this.  This patch looks fine to me, but
I do not maintain generic vector code throughout the compiler; a
global maintainer will have to approve it.

Mark?  Richard?

The target should be powerpc-*-eabi* because the options above will
turn on SPE anyhow.  This way we can test this behavior on generic
powerpc-eabi as well.
