Simplify by re-ordering parameters of cmCompiledGeneratorExpression::Evaluate so that frequently used parameters are before less frequently used parameters. This allows with little extra arguments to get rid of one Evaluate overload, which makes it easier to implement the cmGeneratorExpression::Evaluate utility. The latter would otherwise need four overloads.
