Sse optimized the Scalar & Vector fp-to-fp conversion instructions (MNPZ & IX); added the related Tests (AMNPZ & IX). Small refactoring of existing instructions. (#676)
* Nit. * Update InstEmitSimdCvt.cs * Update VectorHelper.cs * Update InstEmitSimdArithmetic.cs * Update CpuTestSimd.cs * Superseded.
