Set Foundation.Data.SubSequence to be RangeReplaceable

gribozavr · gribozavr · commit eba75508e686 · 2016-09-15T20:20:14.000-07:00
RangeReplaceableCollection.SubSequence should be a
RangeReplaceableCollection.  Data implements RangeReplaceableCollection,
but sets SubSequence to MutableRandomAccessSlice that is not a
RangeReplaceableCollection.

This commit changes Foundation.Data.SubSequence to
MutableRangeReplaceableRandomAccessSlice.

Fixes rdar://problem/28330713.
