Separate patch or into the original one?  We needed element_mode because
TYPE_MODE wouldn't work for a vector_mode so it still somehow fits.

Apart from that, out of curiosity, do we want the same optab mechanism
(try widening/widened op if the original one failed) for vector types as
well in the future?
