		Location	loc,
		presburger::BoundType	type,

		bool	closedUB = `false`
	)

Reify a bound for the given index-typed value in terms of SSA values for which stopCondition is met.

If no stop condition is specified, reify in terms of the operands of the owner op.

By default, lower/equal bounds are closed and upper bounds are open. If closedUB is set to "true", upper bounds are also closed.

Example: %0 = arith.addi a, b : index %1 = arith.addi %0, c : index

If stopCondition evaluates to "true" for %0 and c, "%0 + %c" is an EQ bound for %1.
If stopCondition evaluates to "true" for a, b and c, "%a + %b + %c" is an EQ bound for %1.
Otherwise, if the owners of a, b or c do not implement the ValueBoundsOpInterface, no bound can be computed.
