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

I tried to move the getNearestOption() to it's only client - EmitUnknownDiagWarning() but it turned out to be a significant change because of clang/Basic/DiagnosticGroups.inc use in DiagnosticIDs.cpp.
I suggest we leave that for eventual future refactoring since it would blow up scope of this patch a lot.
