Use quiet NaNs instead of signaling ones
I see no good reason why the NaN returned when reading "nan" as a
double should be a signaling one; a quiet one should be just fine.
[ChangeLog][QtCore][QLocale] The NaN obtained when reading "nan" as a
floating-point value is now quiet rather than signaling.
[ChangeLog][QtCore][QTextStream] The NaN obtained when reading "nan"
as a floating-point value is now quiet rather than signaling.
