ad4b66fd9b [ORC-RT] Specialize non-coalescing-IntervalMap to allow non-comparable values. 
In non-coalescing IntervalMaps the value type should not be requried to be
equality-comparable.

c151e8428a Revert "[ORC-RT] Add IntervalMap and IntervalSet collections." 
This reverts commit ab59185fbfb15c9ce5a64e3aacd3a8c7f6a97621.

It looks like this commit is missing interval_set_test.cpp.

ab59185fbf [ORC-RT] Add IntervalMap and IntervalSet collections. 
IntervalMap is an optionally-coalescing map -- it uses half-open ranges as keys,
allows lookups based on elements of the ranges (returning an iterator to the
containing range) and optionally coalesces adjacent ranges that have the same
value.

IntervalSet is an optionally-coalescing set based on IntervalMap.

These collections will be used to store and lookup metadata section ranges,
e.g. unwind-info ranges.
