This is a patch to fix multiply of v2i64. Today, on SSE4.1, we map a
multiply of v2i64 to pmuldq which does two 32 bit multiples that
generates two 64 bit results, which is incorrect. This patch removes
that and instead lowers it to set of vector code that works for
SSE2+. Please let me know if you have any comments.
