- change for Nereids
1. add a variable length parameter to the ctor of Count for a good error reporting of Count(a, b)
2. refactor StringRegexPredicate, let it inherit from ScalarFunction
3. remove useless class TypeCollection
4. use catalog.Type.Collection to check expression arguments type
5. change type coercion for TimestampArithmetic, divide, integral divide, comparison predicate, case when and in predicate. Let them same as legacy planner.
- change for legacy planner
1. change the common type of floating and Decimal from Decimal to Double
1. remove forcing nullable for slot on EmptySetNode.
2. order by xxx desc should use nulls last as default order.
3. don't create runtime filter if runtime filter mode is OFF.
4. group by constant value need check the corresponding expr shouldn't have any aggregation functions.
5. fix two left outer join reorder bug( A left join B left join C).
6. fix semi join and left outer join reorder bug.( A left join B semi join C ).
7. fix group by NULL bug.
8. change ceil and floor function to correct signature.
9. add literal comparasion for string and date type.
10. fix the getOnClauseUsedSlots method may not return valid value.
11. the tightness common type of string and date should be date.
12. the nullability of set operation node's result exprs is not set correctly.
13. Sort node should remove redundent ordering exprs.
1. generate lots of aggregate functions
2. support `group_concat(columns order by order_columns)` grammer
3. support and generate array aggregate/scalar functions, like `array_union`. we should support array grammar in the future, e.g. `select [1, 2, 3]`
4. add `checkLegalityBeforeTypeCoercion` and `checkLegalityAfterRewrite` function to check the legality of expression before type coercion and after rewrite, copy the semantic check of `FunctionCallExpr` to the checkLegality; remove the `ForbiddenMetricTypeArguments`; move the check of aes/sm4 crypto function from translator to checkLegalityBeforeTypeCoercion
5. refactor the `NullableAggregateFunction`: distinct is the first parameter, alwaysNullable is the second parameter; Fix some wrong initialize order: some function invoke super(distinct, alwaysNullable) but some function invoke super(alwaysNullable, distinct)
## Problem summary
This pr support
1. `numbers` TableValuedFunction for nereids test, like `select * from numbers(number = 10, backend_num = 1)`
2. bitmap/hll aggregate function
3. support find variable length function in function registry, like `coalesce`
4. fix a bug that print nerieds trace will throw exception because use RewriteRule in ApplyRuleJob, e.g: `AggregateDisassemble`, introduced by #13957
support distinct count with group by clause.
for example:
SELECT count(distinct c_custkey + 1) FROM customer group by c_nation;
TODO: support distinct count without group by clause.
1. For some related rules, we need to execute them together to get the expected plan.
2. Add session variables to avoid fallback to stale planner when running regression tests of nereids for piggyback.
