Description

LUCENE-10366 / LUCENE-10376 found that the loop unrolling isn't necessary anymore. ~~SOLR-15405~~ implemented the little endian loop unrolling, but this can be simplified to avoid issues in the future.

Example of what is needed: https://github.com/apache/lucene/pull/592 and https://github.com/apache/lucene/pull/602

  @Override
  public final int readVInt() throws IOException {
    // this can make JVM less confused (see LUCENE-10366)
    return super.readVInt();
  }

  @Override
  public final long readVLong() throws IOException {
    // this can make JVM less confused (see LUCENE-10366)
    return super.readVLong();
  }
