[PATCH] D49736: [Basic] Emit warning flag suggestion only in case there's existing flag *similar* to the unknown one

I like that idea! It looks like it's living in a wrong place anyway as it doesn't need access to any of implementation details (private members) of DiagnosticID. I would still like to preserve it as a function so this block of code has clear semantics and interface. 
How about I refactor it to a static free function in Warnings.cpp?
