Description

Currently, RelBuilder.in(e, constant(1), constant(2), constant(1)) throws, as follows:

java.lang.IllegalArgumentException: Ranges may not overlap, but received [1..1] and [1..1]
	at com.google.common.base.Preconditions.checkArgument(Preconditions.java:146)
	at com.google.common.collect.ImmutableRangeSet$Builder.add(ImmutableRangeSet.java:585)
	at org.apache.calcite.rex.RexBuilder.toSarg(RexBuilder.java:1374)
	at org.apache.calcite.rex.RexBuilder.makeIn(RexBuilder.java:1310)
	at org.apache.calcite.tools.RelBuilder.in(RelBuilder.java:612)

Since the SQL expression e IN (1, 2, 1) is valid, the corresponding call to RelBuilder.in should be valid also.
