Convert packed single-precision (32-bit) floating-point elements in a to
packed half-precision (16-bit) floating-point elements USING NEAREST ROUNDING.
Normally rounding is done according to the imm8[2:0] 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 // round up
- _MM_FROUND_TO_ZERO // truncate
- _MM_FROUND_CUR_DIRECTION // use MXCSR.RC; see _MM_SET_ROUNDING_MODE
HOWEVER here only nearest rounding is supported, this is ensured statically.
Note: Preserve infinities, sign of zeroes, and NaN-ness.
