Nate Cook c6183ee71b Add RangeSet and discontiguous collection operations (#28161) ...

This adds the RangeSet and DiscontiguousSlice types, as well as collection
operations for working with discontiguous ranges of elements. This also adds
a COWLoggingArray type to the test suite to verify that mutable collection
algorithms don't perform unexpected copy-on-write operations when mutating
slices mid-operation.
