      Description

      The FIRST_VALUE, LAST _VALUE functions go through standardization process in AnalyticExpr where they may be rewritten with different number of parameters or with different window frame. In order for an external FE to leverage this standardization, some minor changes are needed to allow overriding of creation of a FunctionCallExpr.
