Synopsis
 _mm256_getmant_pd(__m256d a, _MM_MANTISSA_NORM_ENUM interv, _MM_MANTISSA_SIGN_ENUM sc);
Description
Normalize the mantissas of packed double-precision (64-bit) floating-point elements in "a", and store the results in "dst". This intrinsic essentially calculates "±(2^k)*|x.significand|", where "k" depends on the interval range defined by "interv" and the sign depends on "sc" and the source sign. [getmant_note]
Operation
FOR j := 0 to 3
	i := j*64
	dst[i+63:i] := GetNormalizedMantissa(a[i+63:i], sc, interv)
ENDFOR
dst[MAX:256] := 0
