Join function

[anderson-joyle]

Join(t1, t2, LeftRecord.id = RightRecord.refid) //JoinType.Inner by default
Join(t1, t2, LeftRecord.id = RightRecord.refid, JoinType.Inner) // JoinType.Inner / JoinType.Left / JoinType.Right / JoinType.Full
Join(t1, t2, LeftRecord.id = RightRecord.refid, JoinType.Inner, LeftRecord.id As NewId, ...) // Renaming columns to avoid name collision

            for (var i = 1; i < carg; i++)

Suggestion: start from ScopeArgs instead of 1; we don't need to do any of the logic inside this loop for any of the scope arguments, since they have already been visited (we'd need to move line 4655 (argTypes[i] = _txb.GetType(args[i])) to line 4575 after we visited it

t1, t2

We should have tests for renaming the left/right scopes:

Join(
    t1 As MyLeft,
    t2 As MyRight,
    MyLeft.Id = MyRight.SupplierId,
    JoinType.Inner,
    MyRight.Fruit As Fruit)
