Michael Liao 44c2d61b67 Add support for FP_ROUND from v2f64 to v2f32
- Due to the current matching vector elements constraints in
  ISD::FP_ROUND, rounding from v2f64 to v4f32 (after legalization from
  v2f32) is scalarized. Add a customized v2f32 widening to convert it
  into a target-specific X86ISD::VFPROUND to work around this
  constraints.
