Convert packed single-precision (32-bit) floating-point elements in a to packed half-precision (16-bit) floating-point elements, and store the results in dst.
Rounding is done according to the rounding[3:0] parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT
// round to nearest_MM_FROUND_TO_NEG_INF
// round down_MM_FROUND_TO_POS_INF
