With this simple change, the speedup as compared to commit 18f048424 is
now 37 % for the benchmark given in the previous commit. This is because
optimized swap() only needs to swap the raw pointers, which is certainly
less work than the three move assignments on SGSharedPtr (not raw
pointers) done by std::swap().
To benefit from this, write code like:
using std::swap; // now useless for SGSharedPtr, but idiomatic
swap(ptr1, ptr2); // *not* std::swap()!
