Use ExprMutationAnalyzer in performance-for-range-copy
Summary:
This gives better coverage to the check as ExprMutationAnalyzer is more
accurate comparing to isOnlyUsedAsConst.
Majority of wins come from const usage of member field, e.g.:
for (auto widget : container) { // copy of loop variable
if (widget.type == BUTTON) { // const usage only recognized by ExprMutationAnalyzer
// ...
}
}
