What is the fastest way to read 128 packed integers from a ByteBuffer?

 * `readLongs` just reads 2*bitsPerValue longs from the ByteBuffer, it serves as
   a baseline.
 * `decodeNaiveFromBytes` reads a byte[] and decodes from it. This is what the
   current Lucene codec does.
 * `decodeNaiveFromLongs` decodes from longs on the fly.
 * `decodeSimpleSIMD` is a simple implementation that relies on how Java's C2
   compiler recognizes some patterns and uses SIMD instructions.
 * `decodeSIMD` is a more complex implementation that both relies on the C2
   compiler and encodes 8 bytes, 4 shorts or 2 ints in a long in order to
   decompress multiple values at once.

Now what about decoding and computing a prefix sum of the decoded values?

 * `naiveDecodeAndPrefixSum` uses the fastest SIMD decoding from above and then
   runs a prefix sum with a for loop
 * `naiveDecodeAndUnrolledPrefixSum` uses the fastest SIMD decoding from above
   and then runs an unrolled prefix sum
 * `mergeDecodeAndPrefixSum` runs the prefix sum within the decoding logic, when
   longs are still storing 2 packed integers
