Now that we have more types handled for zext/sext and trunc, it is possible to get more types working for the vector float to integer conversions. This patch adds fp16, widening and narrowing vector support to handle more types. The smaller types wil be expanded to the size of the larger element type. A couple of case require more awkward truncates to get working as they go from illegal to illegal types.
