Creates clause with a list of variables VL.

Parameters

StartLoc	Starting location of the clause.
LParenLoc	Location of '('.
ColonLoc	Location of ':'.
EndLoc	Ending location of the clause.
VL	The variables in the clause.
QualifierLoc	The nested-name qualifier with location information
NameInfo	The full name info for reduction identifier.
Privates	List of helper expressions for proper generation of private copies.
LHSExprs	List of helper expressions for proper generation of assignment operation required for copyprivate clause. This list represents LHSs of the reduction expressions.
RHSExprs	List of helper expressions for proper generation of assignment operation required for copyprivate clause. This list represents RHSs of the reduction expressions. Also, variables in these expressions are used for proper initialization of reduction copies.
ReductionOps	List of helper expressions that represents reduction expressions: LHSExprs binop RHSExprs; operator binop(LHSExpr, RHSExpr); <CutomReduction>(LHSExpr, RHSExpr); Required for proper codegen of final reduction operation performed by the reduction clause.
PreInit	Statement that must be executed before entering the OpenMP region with this clause.
PostUpdate	Expression that must be executed after exit from the OpenMP region with this clause.
