* When `--enable-var-scope` is active, `lib/FileCheck.cpp#clearLocalVars` gets called. * That function loops through `GlobalNumericVariableTable` and then calls `NumericVariable::clear` on most items. It also removes them from `GlobalNumericVariableTable`. * When reassigning an already cleared variable, `Pattern::match` calls `NumericVariable::setValue`, but it doesn't reinsert it into `GlobalNumericVariableTable`. Therefore, the next time `clearLocalVars` is called, it won't be able to loop through the variables. Fix it by reinserting them in `GlobalNumericVariableTable` inside `Pattern::match`.
