           Summary: Add raw_svector_ostream variant for creating temporary
                    strings.

          Platform: PC

With the proliferation of raw_ostream, its becoming common to have code which
creates a small string just for streaming into:
--
    llvm::SmallString<256> NewSyntax;
    llvm::raw_svector_ostream OS(NewSyntax);
    OS << '.' << FieldName->getName() << " = ";
    return OS.str();
--
it would be nice to have a raw_ostream version which included the small string.
Something like:
--
  return (llvm::raw_tmp_ostream() << '.' << FileName->getName() << " =
").str();
--

Good idea, bad idea?
