Introduce getMergedInto(RevCommit commit, Collection<Ref> refs)

In cases where we need to determine if a given commit is merged
into many refs, using isMergedInto(base, tip) for each ref would
cause multiple unwanted walks.

getMergedInto() marks the unreachable commits as uninteresting
which would then avoid walking that same path again.

Using the same api, also introduce isMergedIntoAny() and
isMergedIntoAll()
