Function `_mm_mask_fmul_round_sch`

#[target_feature(enable = "avx512fp16")]
pub fn _mm_mask_fmul_round_sch(src: __m128h, k: __mmask8, a: __m128h, b: __m128h, ROUNDING: i32) -> __m128h

Multiply the lower complex numbers in a and b, and store the results in dst using writemask k (the element is copied from src when mask bit 0 is not set). Each complex number is composed of two adjacent half-precision (16-bit) floating-point elements, which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1].

Rounding is done according to the rounding parameter, which can be one of:

_MM_FROUND_TO_NEAREST_INT | _MM_FROUND_NO_EXC : round to nearest and suppress exceptions
_MM_FROUND_TO_NEG_INF | _MM_FROUND_NO_EXC : round down and suppress exceptions
_MM_FROUND_TO_POS_INF | _MM_FROUND_NO_EXC : round up and suppress exceptions
_MM_FROUND_TO_ZERO | _MM_FROUND_NO_EXC : truncate and suppress exceptions
_MM_FROUND_CUR_DIRECTION : use MXCSR.RC - see _MM_SET_ROUNDING_MODE
