<pre>We currently always prefer the fp domain for vector instructions, I think
mainly to minimize codesize, but some targets (e.g. more recent Intel big
cores) can execute the integer equivalent instructions on more ports and can
easily absorb the codesize increase in the frontend.
We should be able to override the preferred domain for specific target cpus,
although maybe still always chose fp for min codesize cases.</pre>
