The same coding standards suggest to use llvm:StringStream instead, but I cannot find that class anywhere; furthermore, the header file where it was supposed to be (according to the coding standards) doesn't even exist.

This doesn't really answer your question. Instead I offer information to the llvm community: C++ 11 offers these new functions in <string>:
string to_string(int val);
string to_string(unsigned val);
string to_string(long val);
string to_string(unsigned long val);
string to_string(long long val);
string to_string(unsigned long long val);
string to_string(float val);
string to_string(double val);
string to_string(long double val);
The only place I know of in current use where they are not implemented is Apple's v4.2 libstdc++. I believe they've been in gcc and VC++ for several years. They are also in libc++.
