[Bug c++/34470] [4.3.0 regression] spurious "is used uninitialized" from auto_ptr

Ooh, it gets worse.  The spurious diagnostic is a symptom of an incorrect
optimization.  In normal control flow, the result of get_hash is assigned to a
synthetic variable, D.13336, and that variable is used to call operator delete
in basic block 14.  However, an exception might transfer control to label L1
(not a basic block?!) which calls operator delete on hash$_M_ptr, which has
never been initialized.
