Re-write AES/GCM assembly codes with smaller footprints and
small performance gain. Handling the partial blocks differently that
computes partial block to AES states and re-assembles to a complete
block and then computes a full-block hash.
Added gcm_update() to update the last partial block hash value and
generate the final digest.
