Introduce a helper type "Intervals" that contains sets of sorted
disjoint ranges corresponding to live ranges within a function.
Example: the Intervals set "{ [0,1), [4,10) }" would indicate that
something is live starting at instruction 0, then up to but not
including instruction 1, then dead from 1-3, then live again at
instruction 4 up to (but not including) instruction 10.
This patch provides APIs for constructing interval sets, testing to
see whether two sets overlap, and unioning/merging together two
intervals sets.
Updates #62737.
Updates #65532.
