I notice there's some refactor in vectorizable_conversion
for code_helper,so I've adjusted my patch to that.
Here's the patch I'm going to commit.
We have already use intermidate type in case WIDEN, but not for NONE,
this patch extended that.

We have already use intermidate type in case WIDEN, but not for NONE,
this patch extended that.
