IList<T> view operators from Stephen Cleary

Merge some or all of the operators from Stephen Cleary:

Operators for IEnumerable<T> lifted from List<T>/Array:
  int IndexOf<T>(this IEnumerable<T> source, T value)
  int IndexOf<T>(this IEnumerable<T> source, Func<T, bool> predicate) // 
List<T>.FindIndex
  int LastIndexOf<T>(this IEnumerable<T> source, T value)
  int LastIndexOf<T>(this IEnumerable<T> source, Func<T, bool> 
predicate) // List<T>.FindLastIndex

Operators for IList<T> lifted from List<T>/Array:
  IList<T> AsReadOnly<T>(this IList<T> list)
  void CopyTo<T>(this IList<T> list, int index, IList<T> destination, int 
destinationIndex, int count)
  void CopyTo<T>(this IList<T> list, IList<T> destination, int 
destinationIndex)
  void CopyTo<T>(this IList<T> list, IList<T> destination)
  int LastIndexOf<T>(this IList<T> list, T value)
  int LastIndexOf<T>(this IList<T> list, Func<T, bool> predicate) // 
List<T>.FindLastIndex

Operators optimized for IList<T> from Enumerable (.NET 3.5):
  IList<TResult> Select<TSource, TResult>(this IList<TSource> list, 
Func<TSource, TResult> selector)
  IList<TResult> Select<TSource, TResult>(this IList<TSource> list, 
Func<TSource, int, TResult> selector)
  IList<T> Skip<T>(this IList<T> list, int offset)
  IList<T> Take<T>(this IList<T> list, int count)
  IList<T> Reverse<T>(this IList<T> list)
  T Last(this IList<T> list, Func<T, bool> selector)
  T LastOrDefault(this IList<T> list, Func<T, bool> selector)

Operators optimized for IList<T> from EnumerableEx (Rx):
  IList<T> Repeat<T>(this IList<T> list, int count)
  IList<TResult> Zip<TFirst, TSecond, TResult>(this IList<TFirst> first, 
IList<TSecond> second, Func<TFirst, TSecond, TResult> zipper)
  IList<T> Memoize<T>(this IList<T> list)
  IList<T> MemoizeAll<T>(this IList<T> list)

Sources optimized for IList<T> from EnumerableEx (Rx):
  IList<T> Return<T>(T source)
  IList<T> Repeat<T>(T source, int count)
  IList<T> Concat<T>(params IList<T>[] others)
  IList<T> Concat<T>(IList<IList<T>> lists)
  IList<T> Generate<T>(int count, Func<T> generator)
  IList<T> Generate<T>(int count, Func<int, T> generator)

My own sequence/list operators:
 Zip (3-argument version):
  IEnumerable<TResult> Zip<TFirst, TSecond, TThird, TResult>(this 
IEnumerable<TFirst> first, IEnumerable<TSecond> second, 
IEnumerable<TThird> third, Func<TFirst, TSecond, TThird, TResult> zipper)
  IList<TResult> Zip<TFirst, TSecond, TThird, TResult>(this IList<TFirst> 
first, IList<TSecond> second, IList<TThird> third, Func<TFirst, TSecond, 
TThird, TResult> zipper)
 Flatten:
  IEnumerable<T> Flatten<T>(this IEnumerable<IEnumerable<T>> list)
  IList<T> FlattenList<T>(this IList<IList<T>> list)
 Select (bidirectional projection):
  IList<TResult> Select<TSource, TResult>(this IList<TSource> list, 
Func<TSource, TResult> selector, Func<TResult, TSource> reverseSelector)
 Slice:
  IList<T> Slice<T>(this IList<T> list, int offset, int count)
  IList<T> Step<T>(this IList<T> list, int step)
 CopyBackward:
  void CopyBackward<T>(this IList<T> list, int index, IList<T> 
destination, int destinationIndex, int count)
