Merge range predicates

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

An AND predicate combining range predicates that share the same operands can often be merged into a single BETWEEN predicate predicate comparing the left operand with the two right operands.

Using Settings.transformPatternsMergeRangePredicates, the following transformations can be achieved:

-- With Settings.transformPatternsMergeRangePredicates active, this:
SELECT * FROM tab WHERE x >= a AND x <= b;

-- ... is transformed into the equivalent expression:
SELECT * FROM tab WHERE x BETWEEN a AND b;
