Synopsis
 _mm256_permutex2var_ps(__m256 a, __m256i idx, __m256 b);
Description
Shuffle single-precision (32-bit) floating-point elements in "a" and "b" across lanes using the corresponding selector and index in "idx", and store the results in "dst".
Operation
FOR j := 0 to 7
	i := j*32
	off := idx[i+2:i]*32
	dst[i+31:i] := idx[i+3] ? b[off+31:off] : a[off+31:off]
ENDFOR
dst[MAX:256] := 0
