VCOMPRESSPS - COMPRESS Packed Single
VCOMPRESSPS xmm1/m128{k1}{z}, xmm2 (V5+VL
__m128 _mm_mask_compress_sd(__m128 s, __mmask8 k, __m128 a)
__m128 _mm_maskz_compress_sd(__mmask8 k, __m128 a)
void _mm_mask_compressstoreu_sd(void* d, __mmask8 k, __m128 a)
If each bit of (2) is set, the corresponding element of (1) is copied to (3), packed tightly from the lowest position.
If (3) is XMM register and {z} is specified (_maskz_ intrinsic used), upper elements of (3) are zero cleared.
If (3) is XMM register and {z} is not specified (_mask_ intrinsic used), upper elements of (3) are left unchanged (copied from s).
If (3) is memory (_compressstoreu_ intrinsic used) , upper elements of (3) are untouched.

void _mm256_mask_compressstoreu_sd(void* d, __mmask8 k, __m256 a)
If each bit of (2) is set, the corresponding element of (1) is copied to (3), packed tightly from the lowest position.
If (3) is YMM register and {z} is specified (_maskz_ intrinsic used), upper elements of (3) are zero cleared.
If (3) is YMM register and {z} is not specified (_mask_ intrinsic used), upper elements of (3) are left unchanged (copied from s).
If (3) is memory (_compressstoreu_ intrinsic used) , upper elements of (3) are untouched.
