[PATCH] Replace std::auto_ptr with std::unique_ptr in IR unittests

[Xan López]

std::auto_ptr is deprecated in GCC 5.x, so this will not compile out
of the box. We also seem to be using std::unique_ptr all over the
place anyway.

The unit test seems to run just fine after the change.

Subject: [PATCH] Replace std::auto_ptr with std::unique_ptr

std::auto_ptr is deprecated in GCC 5.0, and we are already using std::unique_ptr all over the place.
