s390 (simd): Instruction to consider implementing #50

Intel currently has instructions for converting int32 to float (cvtdq2ps) and float to int32 (cvttps2dq). Similarly, on s390 we have instructions for int64 to double (vcdg/vcdlg), double to int64 (vcgd /vclgd) and float to int32 (vfi), but not an instruction for int32 to float.
