      Description

      Add the Base64 Decode intrinsic for x86 to utilize AVX-512 for acceleration. Also allows for performance improvement for non-AVX-512 enabled platforms. Due to the nature of MIME-encoded inputs, modify the intrinsic signature to accept an additional parameter (isMIME) for fast-path MIME decoding.
