Note that vec_pack works for unsigned as well.
For vec_unpack[hl] of unsigned you can do a vec_merge[hl] instead (with the
first arg a zero vector).

Ahh, sorry for wasting your time. I didn't notice the signed requirement, which
is why it didn't work.

Oh my bad, I got it backwards
vector unsigned long long unpackedl, unpackedr;
vector unsigned int packed;
packed = vec_pack(unpackedl, unpackedr);
unpackedl = vec_unpackh(packed);
unpackedr =

What should the semantics of this be? There are four 32-bit elts each
in packedl and packedr, which of those go where in unpacked?
I think what you want to do can be expressed with just two or maybe

vector unsigned long long unpacked;
vector unsigned int packedl, packedr;
unpacked = vec_pack(packedl, packedr);
packedl = vec_unpackh(unpacked);
packedr = vec_unpackl(unpacked);
