SageInterface::createTempVariableForExpression

Given an expression and an exact attached insertion anchor, atomically inserts a temporary variable immediately before the anchor and publishes its symbol. The returned variable‐reference expression can be used instead of the original expression. The optional SgAssignOp reevaluates the expression. Reference types are represented by pointer temporaries.
