llvm/lib/Support/NativeFormatting.cpp:244]: (style) Variable 'Len' is modified
but its new value is never used.

Source code is

  unsigned Len;
  Len = format(Spec.c_str(), N).snprint(Buf, sizeof(Buf));
  if (Style == FloatStyle::Percent)
    ++Len;
  S << Buf;
  if (Style == FloatStyle::Percent)
    S << '%';
}

I am not sure if local variable 'Len' needs to be used in some
way, or can be safely deleted.
