Disallow StringRef assignment from temporary std::strings.
Similar to r283798, this prevents accidentally referring to temporary
storage that goes out of scope by the end of the statement:
someStringRef = getStringByValue();
someStringRef = (Twine("-") + otherString).str();
Note that once again the constructor still has this problem:
StringRef someStringRef = getStringByValue();
because once again we occasionally rely on this in calls:
takesStringRef(getStringByValue());
takesStringRef(Twine("-") + otherString);
Still, it's a step.
