The result variables aren't useful, and if you have a breakpoint on a common function you can generate a lot of these. So I changed the code that checks the condition to set ResultVariableIsInternal in the EvaluateExpressionOptions that we pass to the execution. Unfortunately, the check for this variable was done in the wrong place (the static UserExpression::Evaluate) which is not how breakpoint conditions execute expressions (UserExpression::Execute). So I moved the check to UserExpression::Execute (which Evaluate also calls) and made the overridden method DoExecute. llvm-svn: 266093
