[X86] Use vector widening to support sign extend from i1 when the dest type is not 512-bits and vlx is not enabled.
Previously we used a wider element type and truncated. But its more efficient to keep the element type and drop unused elements.
If BWI isn't supported and we have a i16 or i8 type, we'll extend it to be i32 and still use a truncate.
