> Improve indexOf performance when called multiple times

> Key: LANG-1177

> The indexOf methods search for a single entry in an array.
> This works fine when only the first matching entry is needed, however it is
> not so efficient when all matches are needed (because of the setup/teardown
> overheads).
> It might be useful to introduce an indexesOf method that returns a BitSet
> containing all the matches.
> This can then be used in the removeAllOccurrences methods.
