Function _mm512_maskz_roundscale_round_ph
#[target_feature(enable = "avx512fp16")]
pub fn _mm512_maskz_roundscale_round_ph(k: __mmask32, a: __m512h, IMM8: i32, SAE: i32) -> __m512hRound packed half-precision (16-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter
Rounding is done according to the imm8 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: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
