VCVTSH2SD xmm {k}, xmm, xmm
Synopsis
 _mm_mask_cvtsh_sd(__m128d src, __mmask8 k, __m128d a, __m128h b);
Description
Convert the lower half-precision (16-bit) floating-point element in "b" to a double-precision (64-bit) floating-point element, store the result in the lower element of "dst" using writemask "k" (the element is copied from "src" when mask bit 0 is not set), and copy the upper element from "a" to the upper element of "dst".
Operation
IF k[0]
	dst.fp64[0] := Convert_FP16_To_FP64(b.fp16[0])
ELSE
	dst.fp64[0] := src.fp64[0]
FI
dst[127:64] := a[127:64]
dst[MAX:128] := 0
