Florent Rougon bc3404fcbe SGSharedPtr: more efficient copy and move assignment operators 
The copy-and-swap idiom is certainly very cute, but often causes
unnecessary copies. My commit fedafb9352
did exactly that, unfortunately.

Restore the exact same code for the copy-assignment operator as before
commit fedafb935, and add a more efficient implementation for the
move-assignment operator.

As explained by Howard Hinnant in [1] and [2], if some particular piece
of code really needs a strong exception safety guarantee, one can easily
add a specific method for that; this is not a valid reason to make the
code slower for all other places that have no use for such a guarantee!
