Rebased and addressed comments.

- Included all vector, result expansion and float softening in the patch. The latter two are done by simply performing the standard expansion. In the worst case, this can result in up to 4 libcalls, but I think this is preferable to adding a massive number of new ones.
- Replaced the VT operand with an integer constant. For vectors, this is the scalar saturation width.
