[Bug libstdc++/23875] New: operator<<(short) should not call operator<<(long), etc.

[pcarlini at suse dot de]

DR117 is not implemented in the same way of DR118: operator<<(short) calls
operator<<(long), operator<<(unsigned short) calls operator<<(unsigned long), 
operator<<(int) calls operator<<(long), etc... I think the way we implemented
DR118 is better (i.e., following the letter of the resolution, without calling
other inserters/extractors), even if it adds more code for now (*), because
allows the user to specialize, say, only operator<<(long), without affecting
the other inserters.

(*) Then, another project would clean-up and commonize the code in those bodies
to, say, _M_insert and _M_extract.
